Ошибка eperm operation not permitted

I ran

npm config set prefix /usr/local

After running that command,
When trying to run any npm commands on Windows OS I keep getting the below.

Error: EPERM: operation not permitted, mkdir 'C:Program Files (x86)Gitlocal'
at Error (native)

Have deleted all files from

C:Users<your username>.configconfigstore

It did not work.

Any suggestion ?

Running this command was my mistake.

npm config set prefix /usr/local

Path /usr/local is not for windows. This command changed the prefix variable at 'C:Program Files (x86)Gitlocal'

To access and make a change to this directory I need to run my cmd as administrator.

So I did:

  1. Run cmd as administrator
  2. Run npm config edit (You will get notepad editor)
  3. Change prefix variable to C:Users<User Name>AppDataRoamingnpm

Then npm start works in a normal console.

This is occurring because windows is not giving permission to the user to create a folder inside system drive. To solve this:

Right Click

The Folder > Properties > Security Tab

Click on Edit to change Permissions > Select the user and give Full Control to that user.

I recently had the same problem when I upgraded to the new version, the only solution was to do the downgraded

To uninstall:

npm uninstall npm -g

Install the previous version:

npm install npm@5.3 -g

Try update the version in another moment.

I had an outdated version of npm. I ran a series of commands to resolve this issue:

npm cache clean --force

Then:

npm install -g npm@latest --force

Then (once again):

npm cache clean --force

And finally was able to run this (installing Angular project) without the errors I was seeing regarding EPERM:

I had the same problem when I tried to install the npm package AVA. The solution for me was to delete the node_modules folder and force-clean the npm cache:

rm -rf node_modules
npm cache clean --force

I could then install the npm package without a problem.

I had the same problem, after updating npm. Solved it by re-installing latest npm again with:

npm i -g npm

but this time with cmd running in administrating mode.

i did all this because i suspected there was an issue with the update, mostly some missing files.

The Problem I faced (In Windows Computer)

When I was trying to install a couple of npm packages I got the following error:

npm — EPERM: operation not permitted — while npm was trying to rename a file

Here’s my debug snippet for reference, if you’ve faced the similar problem:

The Problem I faced

After carefully checking out the answers from other users, I have created a detailed answer for the community

My Solution for the problem

Follow the mentioned steps

  1. Right-click on the project folder
  2. Go to properties -> Security Tab
  3. Select Users -> Edit
  4. In the Permission for Users section, Full control -> Give a check mark in Allow -> OK
  5. Wait for Windows security to apply the new security rules
  6. Click OK

Simplest way

Hope I am not too late for this post but recently even I too got hit by this issue. And also I had no admin rights on my laptop.

Here is the simplest way I fixed the bug.

  1. Locate the file name .npmrc (it will be in C:Users<user name>.npmrc)
  2. Open it and change the path of prefix= to prefix=C:Users<user name>AppDataRoamingnpm

hope it will be helpful..

If you getting this error in an IDE’s terminal/commands prompt, try delete node_modules, close IDE, and run the npm install command again.
The time when IDE started but still not completed its analysis of node_modules tree is a tricky moment, when packages installation may fail because IDE still scanning node_modules contents.

This error is caused by different problems try the below one of them will work for you!

  • try to run npm as Administrator

  • Run cmd as administrator npm config edit (You will get notepad editor)
    Change Prefix variable to C:Users<User Name>AppDataRoamingnpm

  • The errors went after I disabled my anti-virus (Avast)

  • Sometimes a simple cache clear like the below would fix it.

For those trying to update config

If having trouble updating your npm config, try instead running using the -g flag. This solved the issue on Win 10 for me after trying everything else.

npm config edit -g

I am able to update the config and changes are reflected everywhere. This may be due to running npm in an organizational scope.

This is not the recommended way of using create-react-app according to the React documentation and it may cause problems down the line.|

Same happened with me. I did the same, installed create-react-app globally and it started working but after a few days and a few tweaks and a few updates here and there it stopped working again.

After having to spend 2 hours digging I found this to be the more permanent solution.

This error is caused by having a space in your User name (i.e the name of your machine) for instance my machine name is Themba Alex, npx has an issue when such is the case, the solution to this is to open your terminal and run this command:
npm config edit afterward go to every line that is starting with
;cache=C:UsersThemba AlexAppDataRoamingnpm-cache, remove the ; and remove the space on your username, write the first 6 letters and add "~1" i.e ;cache=C:UsersThemba AlexAppDataRoamingnpm-cache will now be cache=C:UsersThemba~1AppDataRoamingnpm-cache this will solve the issue

After a lot of digging and coming to this, I thought this would solve my problem but it isn’t solving my problem. Even after changing Firstname Lastname to Firstname~1 and to Firstname~Lastname I am getting the same error.
Error: EPERM: operation not permitted, mkdir 'C:UsersFirstname~Lastname' command not found: create-react-app

I found the solution to this. Instead of just changing Firstname Lastname to Firstname~1 or Firstname~Lastname , check what the short name for your Username directory is. You can do this by opening the CMD as an administrator and running dir /x in the parent folder of the folder whose short name you’re trying to find. In this case since you want to know the short name to your Firstname Lastname folder, the parent folder will be C:/Users. So go to C:/Users and run dir /x. You’ll find the short name of your Firstname Lastname folder. It may not necessarily be Firstname~1. In my case, it was FirstnameL~1. After this you can run npm config set cache "C:/Users/<shortname-you-found-with-dir/x>/AppData/Roaming/npm-cache" --global. Now you should be able to run npx create-react-app my-app without any issue.

So I tried doing this and my system is not showing any shortnames, I’m still not able to fix this! Can you help me out?

Recently, when attempting to use the gulp command in the Terminal app, I saw an error message saying Error: EPERM: operation not permitted, uv_cwd. In this tutorial, you’ll learn how to solve this problem.

How to fix: Error: EPERM: operation not permitted, uv_cwd

What causes this error

In my case, the below error appeared when attempting to run the gulp command inside my app project directory in the Terminal app.

$ gulp build
internal/bootstrap/switches/does_own_process_state.js:129
    cachedCwd = rawMethods.cwd();
                           ^

    at require (internal/modules/cjs/helpers.js:72:18) {
  errno: -1,
  code: 'EPERM',
  syscall: 'uv_cwd'
}

This seemed strange to me because I had just used the gulp tool and everything was fine. Then I tried to use the bundle update command, thinking that this can be a hint to localize the problem.

$ bundle update
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted
Traceback (most recent call last):
	9: from /usr/local/bin/bundle:23:in <main>
	8: from /Library/Ruby/Site/2.6.0/rubygems.rb:294:in `activate_bin_path'

/Library/Ruby/Site/2.6.0/rubygems/bundler_version_finder.rb:85:in pwd': Operation not permitted - getcwd (Errno::EPERM)

The error appeared again, but now the error message is self explanatory. It saying that the shell-init cannot access parent directories, and this is because error retrieving current directory.

In my case, this makes sense because I used the Finder to delete my app project catalog and restore it from the backup after trying new things and changed my mind to keep them. Facepalm >_<

Now we know what caused this error.

How to solve it

Once we know what is causing the gulp run to fail, we can use it to solve the problem. It is a really easy process. To solve this problem, we just need to re-enter into our app project directory. Now, step by step guide.


In the Terminal app, type the following command and press the Enter key to go up one level in the directory.


Now, type the following command and press the Enter key to navigate to your working directory (in this example the my_app_dir catalog is used).

Important! In my case the working directory is the catalog of my app project called my_app_dir where the problem has occurred. Change the command above to suit your case.

Conclusion

That’s it, you’re done. Now the gulp should run without the Error: EPERM: operation not permitted, uv_cwd error. So simple isn’t it?

If you are having trouble fixing this problem with the instructions above, but are being able to solve this problem with any another method please describe it in the comment section below. Thanks!

I hope this article has helped you learn how to fix the Error: EPERM: operation not permitted, uv_cwd error. If this article has helped you then please leave a comment :smiley:

  1. FAQs

What is Error: EPERM? {#what-is-error-eperm}

Error: EPERM (Error-Permission) is a common error encountered by developers when trying to perform an operation that requires specific permissions on files or directories. This error typically occurs when the user attempting the operation does not have the required permissions to perform the action, resulting in messages such as «operation not permitted» or «unlink» issues.

Common Causes of Error: EPERM {#common-causes-of-error-eperm}

Error: EPERM can occur due to various reasons, including:

  1. Insufficient file or directory permissions
  2. Running a script or application without sufficient privileges
  3. Interference from antivirus software

How to Fix Error: EPERM {#how-to-fix-error-eperm}

To resolve Error: EPERM, follow these step-by-step solutions:

Solution 1: Modify File Permissions {#solution-1-modify-file-permissions}

If EPERM errors are caused by insufficient file or directory permissions, you can modify the permissions using the following commands:

On Linux and macOS:

chmod -R 755 /path/to/directory

On Windows:

icacls "C:pathtodirectory" /grant:r Users:(OI)(CI)F /T

In both cases, replace /path/to/directory or C:pathtodirectory with the actual path of the affected directory.

Solution 2: Run as Administrator {#solution-2-run-as-administrator}

Running your script or application with administrative privileges can resolve EPERM errors caused by insufficient user permissions:

On Linux and macOS, use the sudo command:

sudo node myscript.js

On Windows, right-click on the command prompt or PowerShell and select «Run as Administrator» before executing your script or application.

Solution 3: Check and Disable Antivirus Software {#solution-3-check-and-disable-antivirus-software}

Antivirus software may interfere with file operations and cause EPERM errors. To fix this issue, temporarily disable your antivirus software and retry the operation. If the issue is resolved, consider adding an exception for the affected file or directory in your antivirus software settings.

Solution 4: Delete Files and Directories Manually {#solution-4-delete-files-and-directories-manually}

If the EPERM error occurs when attempting to delete files or directories, you can try deleting them manually using the following commands:

On Linux and macOS:

rm -rf /path/to/directory

On Windows:

Remove-Item -Recurse -Force "C:pathtodirectory"

In both cases, replace /path/to/directory or C:pathtodirectory with the actual path of the affected directory.

Solution 5: Use a Different Development Environment {#solution-5-use-a-different-development-environment}

If the EPERM error persists, consider using a different development environment, such as a virtual machine or container, to isolate the issue and ensure proper permissions are set.

FAQs {#faqs}

What does EPERM stand for? {#what-does-eperm-stand-for}

EPERM stands for Error-Permission, which indicates a permissions-related error.

Can I ignore EPERM errors? {#can-i-ignore-eperm-errors}

Ignoring EPERM errors is not recommended, as they indicate a lack of required permissions to perform specific operations. Ignoring these errors may result in incomplete or incorrect execution of your script or application.

How do I check file permissions on my system? {#how-do-i-check-file-permissions}

On Linux and macOS, use the ls -l command to check file permissions. On Windows, use the icacls command to view file and folder permissions.

How can I change file ownership on my system? {#how-can-i-change-file-ownership}

On Linux and macOS, use the chown command to change file ownership. On Windows, use the takeown command to take ownership of a file or folder.

Can antivirus software cause EPERM errors? {#can-antivirus-software-cause-eperm-errors}

Yes, antivirus software can cause EPERM errors by interfering with file operations. Temporarily disabling your antivirus software or adding an exception for the affected file or directory can resolve this issue.

This seemed strange to me because I had just used the gulp tool and everything was fine. Then I tried to use the bundle update command, thinking that this can be a hint to localize the problem.

$ bundle update
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Operation not permitted
Traceback (most recent call last):

/Library/Ruby/Site/2.6.0/rubygems/bundler_version_finder.rb:85:in pwd': Operation not permitted - getcwd (Errno::EPERM)

The error appeared again, but now the error message is self explanatory. It saying that the shell-init cannot access parent directories, and this is because error retrieving current directory.

In my case, this makes sense because I used the Finder to delete my app project catalog and restore it from the backup after trying new things and changed my mind to keep them. Facepalm >_<

Now we know what caused this error.

How to solve it

Once we know what is causing the gulp run to fail, we can use it to solve the problem. It is a really easy process. To solve this problem, we just need to re-enter into our app project directory. Now, step by step guide.


In the Terminal app, type the following command and press the Enter key to go up one level in the directory.


Now, type the following command and press the Enter key to navigate to your working directory (in this example the my_app_dir catalog is used).

Important! In my case the working directory is the catalog of my app project called my_app_dir where the problem has occurred. Change the command above to suit your case.

Conclusion

That’s it, you’re done. Now the gulp should run without the Error: EPERM: operation not permitted, uv_cwd error. So simple isn’t it?

I hope this article has helped you learn how to fix the Error: EPERM: operation not permitted, uv_cwd error. If this article has helped you then please leave a comment :smiley:

Thanks for reading!

The npm install step in my Teamcity CI build for an angular app I have been working has been failing intermittently and I finally uncovered the reason.

TL/DR The combination of McAfee Anti-virus and network mounted user AppData folders was the culprit — moving them to an unscanned local folder fixed it.

npm install was failing the build intermittently when run by our build software Teamcity on a windows agent with ugly errors like:

npm ERR! Error: EPERM: operation not permitted
rename 'C:Usersthe-build-userAppDataRoamingnpm-cachewrappy1.0.2packagepackage.json.363dae6043e3d4d0bd28d6ad9849acf4'

Sometimes a simple cache clear like the below would fix it, but other times it was more stubborn.

npm cache clear

I turns out that the default install location for npm is in the running users AppData folder. There are two folders, one for npm prefix folder which is the global install location and another for a cache of packages retrieved from the internet. The default paths are based on the %AppData%Roaming path so typically end up as:

c:UsersYOUR_USER_NAMEAppDataRoamingnpm
c:UsersYOUR_USER_NAMEAppDataRoamingnpm-cache

In my work windows server environment the users AppData folder is actually on a network share under the hood so it follows you around from machine to machine, although to users it appears as a regular folder. It was also monitored by the anti-virus scanner, in this case McAfee, and those folders were not on any scanning exclusion lists.

The combination of network location and McAfee scanning disagreed with node.js and npm meaning that files would appear locked or missing and often generate the not permitted error.

The solution was to move the files to a new location and change the users configuration to use the new paths. It also sped up the builds which was a nice perk!

First move the files to a real ‘local’ path that is ignored by the AV software, in my case e:buildagent, and then change the configuration

"Create new folders"
mkdir E:Buildagentnpm
mkdir E:Buildagentnpm-cache

"move npm prefix and the cache"
robocopy c:Usersthe-build-userAppDataRoamingnpm  E:Buildagentnpm
robocopy c:Usersthe-build-userAppDataRoamingnpm-cache  E:Buildagentnpm-cache /E /MOVE 

"Update the npm config for prefix and cache"
npm config set prefix E:Buildagentnpm
npm config set cache E:Buildagentnpm-cache

Then you may need to change the path environment variable if %AppData%Roamingnpm is on configured to be on your path so that it points to the new destination as set above in the prefix config setting. Either edit it manually or use the excellent RapidEE for the task.

Finally test that npm install still works. With any luck your build should be reliable again.

Как исправить ошибку npm! Ошибка: EPERM: операция не разрешена, переименовать

Я только что обновил npm к 5.4.0. Теперь, когда я хочу установить пакет npm, я получаю следующую ошибку:

D:SourcesDownloadCmsMd.DownloadWeb.Angular>npm install [email protected] --save npm ERR! path D:SourcesDownloadCmsMd.DownloadWeb.Angularnode_modulesfseventsnode_modulesabbrevpackage.json npm ERR! code EPERM npm ERR! errno -4048 npm ERR! syscall unlink npm ERR!

C:UsersMohammadAppDataRoamingnpm-cache_logs2017-09-03T03_25_50_432Z-debug.log 

Я абсолютно уверен, беги CMD как администратор.

Также я проверил D:SourcesDownloadCmsMd.DownloadWeb.Angularnode_modulesfseventsnode_modulesabbrevpackage.json, package.json не существует в пути!

Редактировать: Обновитесь до v5.4.1, все равно получите ту же ошибку, даже невозможно обойтись с —no-optional :-(

1 2 Далее

Это проблема npm 5.4.0 https://github.com/npm/npm/issues/18287

Обходные пути

  • перейти на 5,3
  • попробуйте запустить с —no-optional, т.е. npm install --no-optional
  • 7 --no-optional полностью прибил для меня (@ 5.4.1)!
  • 10 если вы открыли VSCode затем закройте его и попробуйте запустить npm команда будет установлена ​​определенно, переход на более раннюю версию не является решением.
  • 4 Закрытие VS Code и запуск npm i извне работал у меня.

Я смог исправить это, запустив командную строку / bash от имени администратора и закрыв VSCode! Похоже, что VSCode заблокировал некоторые файлы. Возможно, что-то еще может заблокировать эти файлы за вас.

  • 11 Спасибо! В моем случае это была Visual Studio 2015, которая блокировала некоторые файлы.
  • Ага. Спасибо. Очень просто. Закрыл VS Code и решил все мои проблемы.
  • 2 В моем случае Process Explorer неизменно сообщает мне, что виновник блокировки файлов npm пытается удалить … другой node.exe процесс, порожденный npm Бег npm! О, радость, этот инструмент не перестает удивлять… (это в Windows 10, Node 12.11.0, npm 6.11.3)
  • почему, черт возьми vscode не удается установить угловое приложение?
  • +1 Для закрытия любых запущенных процессов, которые могут зависать в файле — у меня была запущена служба vue-cli-service. Закрытие, которое решило это для меня.

Если вы перейдете на версию 5.3 и получите такую ​​же ошибку в Windows, как и я.
После нескольких часов работы с версиями npm я нашел следующее решение:

1. Загрузите последнюю рекомендованную версию nodejs, в эти дни node-v6.11.3-x64
2. Удалить nodejs с этим.
3. Перейти к C:Users{YourUsername}AppDataRoaming папку и удалить npm а также npm-cache папки
4. Запустить установщик nodejs снова и установите его
5 Обновите npm до 5.3 с помощью npm i -g [email protected] командная строка

Теперь вы должны использовать npm без каких-либо проблем.

Я исправил, понизив npm с 5.4.0 до версии 5.3

npm i -g [email protected] 

Надеюсь, это поможет вам

Я попробовал это решение, найденное в блоге Как исправить Node.js

просто используйте

npm cache clean 

в окнах, если он отказывается использовать

npm cache clean --force
  • 1 У меня не работает. Windows в CI на VSTS (теперь Azure DevOps)

У меня была такая же проблема в Windows.

Источник проблемы прост, это разрешение доступа к папкам и файлам.

В папке вашего проекта вам нужно

  1. После клонирования проекта измените свойства папки и измените права пользователя (предоставьте полный доступ текущему пользователю).
  2. Удалите параметр только для чтения из папки проекта. (Шаги 1 и 2 занимают много времени, потому что они копируются на все дерево ниже).
  3. Внутри папки проекта переустановите узел (npm install переустановить -g)
  4. Отключите антивирус. (по желанию)
  5. Отключите брандмауэр. (по желанию)
  6. Перезагрузите компьютер.
  7. Очистить кеш npm (очистить npm)
  8. Установите зависимости вашего проекта (установка npm)

После этого ошибка «Ошибка: EPERM: операция не разрешена, разорвать связь«больше не будет отображаться.

Не забудьте повторно активировать брандмауэр и антивирус при необходимости.

У меня была такая же проблема, и все, что мне нужно было сделать, это войти в npm

npm login

или альтернативно

npm add user // обратитесь к документации по параметрам

Закройте все IDE, например код Visual Studio. запустите команду npm install через командную строку node.js. Наслаждайтесь !

  • В некоторых случаях требуется перезагрузка системы.
  • Также проверьте файл .NPMRC

кеш чист и npm обновить до последней версии с принудительной работой для меня

npm cache clean --force npm install -g [email protected] --force 

В моем случае проблема заключалась в том, Машинопись не устанавливал. Хотя я установил Node и Angular. Чтобы проверить, установили ли вы машинописный текст или нет

Run this command: tsc -v 

Если нет, то для установки машинописи

Run this command: npm install -g typescript 

И, наконец, установить необходимые зависимости

Run this command: npm install 

в корневой папке проекта.

—- Надеюсь, это кому-то поможет —-

Для меня это сработало в bash из пакета git попробуйте:

C:Program FilesGitbinbash.exe 

тогда:

npm install [email protected] 

Кажется, есть много решений, которые работали с понижением версий npm. Для меня решение было

npm install -force 

Я попробовал понизить версию npm, изменив конфигурацию префикса npm, чтобы он соответствовал каталогу npm, и очистил кеш. Ни один из них не работал, но, очевидно, они работали для других, так что, возможно, стоит попробовать.

Для меня в Windows проблема была слишком длинная длина пути. Я переместил проект на путь меньшей длины, и он сработал.

У меня были эти логи в Windows. Я сделал следующее

  • Закройте код Visual Studio
  • Запустите командную строку от имени администратора

Если все вышеперечисленное не помогло вам, возможно, вы захотите

  • перезагрузите вашу систему
  • запустить командную строку от имени администратора
  • запустите команду npm

Удаление package-lock.json устранило это для меня.

та же ошибка приходит ко мне, когда я обновляю версию npm до последней версии 5.4, даунгрейд до версии 5.3.0 полезен. ошибка возникает из npm 5.4, вы можете проверить ее в выпусках в npm 5.4

npm install [email protected] -g 

Исправлено в NPM 5.6.0

Обновление до NPM 5.6.0 решило для меня проблему.

Я хотел запустить npm install с внешнего жесткого диска, так как именно здесь я сохранил свое рабочее пространство с кодом. ОС Windows 10.

Но я получал ту же ошибку, что и исходный пост. Ни один из предыдущих ответов у меня не работал, я перепробовал их все:

  1. удаление nodejs, а затем повторная установка
  2. удаление nodejs, а затем понижение / установка более ранней версии nodejs.
  3. npm install -force
  4. удаление папок из C: Users {YourUsername} AppData Roaming … npm и npm-cache, а затем повторная установка.
  5. очистка кеша npm —force
  6. очистка кеша npm
  7. npm install —g или npm install —global

Для меня сработало следующее:

  1. скопируйте папку из C: Program Files nodejs в D: Program Files nodejs
  2. Затем перейдите в Панель управления Система и безопасность Система
  3. Расширенные настройки системы
  4. Переменные среды
  5. Системные переменные
  6. Дважды щелкните Путь
  7. Добавить новый путь
  8. D: Program Files nodejs
  9. Нажмите ОК
  10. перезагрузите компьютер.
  11. попробуйте установить npm из D: Drive

После всех попыток, включая обновление node / npm, очистку кеша и возврат кода, ничего не помогло, кроме одной простой вещи: Отключение защиты в реальном времени в Windows 10 во время разработки / сборки. Похоже, последние обновления сделали его супер агрессивным.

я использую VsCode и решил эту проблему, остановив сервер приложений, и они запустили npm install. Есть файлы, заблокированные сервером приложений.

Не нужно закрывать IDE, просто убедитесь, что другой процесс не блокирует некоторые файлы в ваших проектах.

Мой был в результате открытия папки моего проекта двумя разными терминалами. я решено это от закрытие всех работающих терминалов (код vs был исключен) и повторное выполнение команды установки.

Я надеюсь, что это помогает кому-то.

NB: удаление node_modules не решило эту проблему.

Для окон,

  1. Загрузите последнюю рекомендованную версию nodejs, в эти дни node-v6.11.3-x64
  2. Удалите с ним nodejs.
  3. Перейти к C:Users{YourUsername}AppDataRoaming папку и удалить npm а также npm-cache папки
  4. Запустить установщик nodejs снова и установите его
  5. По умолчанию npm 3.10.10 должен быть установлен вместе с node-v6.11.3-x64.
  6. Это сработало для меня с npm 3.10.10 но не работал с 5.3.X. Также он не работал с более поздними версиями узла (см. Выше node-v6.11.3-x64)

npm cache verify решил мою проблему. Я делал: ng new my-app и я столкнулся с аналогичной ошибкой

У меня версия узла: 10.16.0
npm v 6.9.0

Моя проблема заключалась в выполнении команды (npm audit fix all). Решил при закрытии VSCODE и без проблем повторно выполнил команду.

Я просто полностью выключил, НЕ переходил в спящий режим, свою машину и перезапустил. Запустил CMD от имени администратора и использовал команду установки npm. Это сработало.

В моем случае я столкнулся с аналогичной проблемой при запуске нескольких экземпляров ‘npm install’ на виртуальной машине, используемой для сборки (Windows)

Поскольку это была виртуальная машина, которая использовалась только для сборки, никакая другая программа не блокировала файлы. Я пытался отключить различные настройки антивируса, но они не помогли. «npm cache clear» и «npm cache verify» работали, но для меня это не было правильным решением, так как я не могу угадать, когда кто-то запустит задание сборки от Jenkins для другого выпуска / среды, что приведет к нескольким экземплярам ‘npm install’ и, следовательно, Я не могу добавить его в сценарий сборки, и я не могу войти в виртуальную машину и каждый раз очищать / удалять папки кеша вручную.

Наконец, после некоторого исследования я закончил запуском «npm install» с отдельным путем кеширования для каждого задания, используя следующую команду:

npm install --cache path/to/some/folder 

Поскольку все задания, выполняющиеся одновременно, теперь имели отдельный путь кэширования, а не общий глобальный путь (Users / AppData / Roaming /), эта проблема была исправлена, поскольку задания больше не пытались заблокировать и получить доступ к одному и тому же файлу, из общего кеша npm.

Обратите внимание, что вы можете установить один пакет с путем кэширования следующим образом:

npm install packageName --cache path/to/some/folder 

Мне не удалось найти этот способ указать путь к кешу в документации npm, но я попробовал, и он сработал. Я использую npm6 и похоже, что он работает с npm5.

[Обратитесь: Как указать папку кеша в npm5 при команде установки?

Это решение должно работать и для других сценариев, хотя может подойти, а может и не подойти.

npm login требуется до publish

Это единственное, что у меня сработало:

npm cache clean --force npm install -g [email protected] --force rm package-lock.json npm i -force 

У меня такая же проблема, просто выполняя установку npm. Запускайте с отключенным антивирусом (если вы используете Защитник Windows, отключите защиту в реальном времени и защиту на основе облака). Это сработало для меня!
