Одна ошибка, с которой вы можете столкнуться в R:

Error in setwd("C:/Users/UserName/Desktop") : 
 cannot change working directory

Эта ошибка возникает, когда вы пытаетесь установить рабочий каталог в R, но неправильно указываете часть пути к файлу.

В этом руководстве рассказывается, как именно исправить эту ошибку.

Как воспроизвести ошибку

Предположим, я пытаюсь установить следующий рабочий каталог в R:

#attempt to set working directory
setwd("C:/Users/Bob/Documents/My Folder Name")

Error in setwd("C:/Users/Bob/Documents/My Folder Name") : 
 cannot change working directory

Я получаю сообщение об ошибке, потому что эта папка не существует на моем компьютере.

Как исправить ошибку

Самый простой способ исправить эту ошибку — изменить путь к файлу, чтобы он указывал на правильную папку:

#set working directory
setwd("C:/Users/Bob/Documents/Correct Folder Name")

Обратите внимание, что я не получаю сообщение об ошибке, потому что R смог успешно изменить рабочий каталог.

Я могу подтвердить, что рабочий каталог успешно изменился, используя функцию getwd() для получения текущего рабочего каталога:

#get current working directory
getwd()

"C:/Users/Bob/Documents/Correct Folder Name"

Распространенные причины ошибок

Существует несколько причин, по которым вы можете получить это сообщение об ошибке в R. Общие причины включают:

  • Вы просто неправильно указали путь к файлу.
  • Вы включили недопустимые символы в путь к файлу.
  • У вас нет разрешения на доступ к пути к файлу.

Если вы столкнулись с этой ошибкой, обязательно проверьте эти три распространенные проблемы и при необходимости исправьте их.

Дополнительные ресурсы

В следующих руководствах объясняется, как исправить другие распространенные ошибки в R:

Как исправить: NA, введенные принуждением
Как исправить: отсутствует значение там, где нужно true/false
Как исправить: неправильное количество индексов в матрице
Как исправить: количество элементов для замены не кратно длине замены

The “cannot change working directory” R file error message is an odd little message in that while it is a coding problem it may not result from an R code mistake. Rather it is a problem that arises from trying to change a root directory to a non-existing name. This makes it an unusual problem and fortunately one that is easy to fix within the R console.

The circumstances of this problem.

The “cannot change working directory” error message occurs when using the setwd() function to change the working directory in the format of setwd(“~/”) or entering an invalid data directory name. Normally a file is placed in the default working directory. However, there are circumstances where you might want to change the current working directory within your r script file. This has the advantage that it automatically resets itself when the project or dataset is reloaded. As a result, it is a handy tool for saving and loading files from a different directory path other than the default directory path. This comes in handy when you know the file location for 2 different files or more in the project directory.

What is causing this problem?

The “cannot change working directory” error message is caused by an operating system not recognizing “~/” as indicating a root directory or pointing to an invalid folder name. As a result, the software is looking for a non-existent folder. This causes it to return this message because it cannot change the working directory.

# r error cannot change working directory r code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("C:/Users/Owner/Documents/R/test")
Error in setwd("C:/Users/Owner/Documents/R/test") :
cannot change working directory

In this case, we got the message because we entered an invalid folder. In most systems using setwd(“~/”) will simply change the working directory to the root directory. However, there are some systems where “~/” is not recognized resulting in this message. Fortunately, small a change in syntax can fix the problem.

How to fix this problem.

Fixing this problem is simply a matter of eliminating the “~/” reference from your script. Because the setwd() function is the set working directory function, you can use it to set the current directory in your code. All you need to do is set it to the file path folder you are looking for. The getwd() function is similar to the dose “dir” command except that it gets you to the current working directory in your r console workspace.

# r error cannot change working directory solution code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("~/")
> getwd()
[1] "C:/Users/Owner/Documents"

To get the same effect as this example R code you simply need to substitute the name of the specific project directory you want to go to in the character string here in place of “~/”. To get the current working directory just use the getwd() function and make the needed adjustments to get the file location folder or absolute filepath that you want as your current directory.

# cannot change working directory r error solution example code
> getwd()
[1] "C:/Users/Owner/Documents/R/error test"
> setwd("C:/Users/Owner/Documents")
> getwd()
[1] "C:/Users/Owner/Documents"

In this example, we simply define the working directory as “C:/Users/Owner/Documents” to make the desired change. It may not be as elegant or short as the other version but it works. In the situation where you have an erroneous folder or file system name simply correct it in the home directory so that it is a valid name.

This is a simple problem to solve but you are only likely to get it by miss typing a folder name. If you get it for “~/” then you just have to specify where you want to put it and it will work. In both cases, you will fix the problem.

Having problems getting Xash to work.

I’ve followed the steps of putting a Xash folder in the root of my SD Card directory and putting the valve folder in there.

When I go to launch the game I get an error «Changing working directory to /sdcard/xash failed.»

I’ve tried a few combinations of the directory.. adding /valve/ to the end of it, putting a space inbetween sd and card since that’s how it appears on my file browser app. I’m lost. :(

You have to set environment variable HOME or the Working Directory however since Terminus thinks you’re Windows and otherwise tries to use C:Users<user>, even though you’re opening a terminal in a non-windows machine (in both cygwin/gitbash/wsl/etc)

However, the check here in the code fails because it’s trying to resolve /home/<user> in the Windows FS, and not the shell’s FS

I honestly am not sure how setting the HOME environment variable workaround would work with this logic

@Eugeny thoughts on maybe trying to open the shell to cwd and if it fails, then open it again with cwd: undefined rather than doing a FS check? I would test it but I can’t get the electron application to start

I’m getting a BSOD on my HP ProBook 430G2 running Windows 7 Pro (64 bit) , so am trying to use the Recovery Manager software to revert back to the factory settings.

On bootup, I press F11 and I get «windows is loading files’ across the bottom, then ‘Starting Windows’, and then the light blue screen with the HP logo (all as I would excpect).  However, shortly after it comes up with an error box stating «Failed to change working directory’

Clicking ‘OK’ (the only option) takes me into a command prompt and leaves me at the ‘x:windowssystem32>’ prompt.

I’ve taken the disk out and accessed it from another device, and it seems that the recovery partition is present.

Image: post content

Is there any way that I can manually enter the commands required to continue the recovery process?

In this article you’ll learn how to deal with the “Error in setwd() : cannot change working directory” in the R programming language.

Table of contents:

Let’s take a look at some R codes in action:

Example 1: Reproduce the Error in setwd() : cannot change working directory

In this section, I’ll explain how to replicate the error message “cannot change working directory” in R.

Let’s assume that we want to set our working directory to a folder called “Some Folder” on our Desktop using the setwd function.

Then, we might try to do that as shown below:

setwd("C:/Users/Joach/Desktop/Some Folder")    # Try to use non-existing folder
# Error in setwd("C:/Users/Joach/Desktop/Some Folder") : 
#   cannot change working directory

Unfortunately, the RStudio console returns the error message “cannot change working directory”.

The reason for this is that the directory we are trying to access does not exist. We might have specified the folder name wrong, or the path before the folder name is not existing.

Example 2: Fix the Error in setwd() : cannot change working directory

We can solve this problem by specifying the path correctly. In this example, the problem was that the folder “Some Folder” does not exist on my Desktop. For that reason, I can avoid the “Error in setwd() : cannot change working directory” by setting the working directory directly to my Desktop:

setwd("C:/Users/Joach/Desktop/")               # Properly specify setwd

Executing the previous R code does not lead to any errors.

One error you may encounter in R is:

Error in setwd("C:/Users/UserName/Desktop") : 
  cannot change working directory

This error occurs when you attempt to set the working directory in R, but you misspell some part of the file path.

This tutorial shares exactly how to fix this error.

How to Reproduce the Error

Suppose I attempt to set the following working directory in R:

#attempt to set working directory
setwd("C:/Users/Bob/Documents/My Folder Name")

Error in setwd("C:/Users/Bob/Documents/My Folder Name") : 
  cannot change working directory

I receive an error because this folder does not exist on my computer.

How to Fix the Error

The easiest way to fix this error is to change the file path to point to the correct folder:

#set working directory
setwd("C:/Users/Bob/Documents/Correct Folder Name")

Notice that I don’t receive an error because R was able to successfully change the working directory.

I can confirm that the working directory successfully changed by using the getwd() function to get the current working directory:

#get current working directory
getwd()

"C:/Users/Bob/Documents/Correct Folder Name"

Common Reasons for Errors

There are several reasons for why you may receive this error message in R. Common reasons include:

  • You simply misspelled the file path.
  • You included invalid characters in the file path.
  • You do not have permission to access the file path.

If you run into this error, make sure to check these three common issues and fix them if necessary.

I’ve new to Linux, only switched around 4 months ago from Windows. I’m trying to install a Minecraft server using this tutorial, and I keep getting this when I try to start the server through systemd and check the status of it:

Loaded: loaded (/etc/systemd/system/minecraft.service; disabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Tue 2022-07-19 22:32:20 PDT; 6s ago
    Process: 21308 ExecStart=/usr/bin/java -Xmx1024M -Xms1024M -jar server.jar nogui (code=exited, status=200/CHDIR)
   Main PID: 21308 (code=exited, status=200/CHDIR)
        CPU: 14ms

Jul 19 22:32:20 myname-ThinkPad systemd[1]: Started Minecraft Server.
Jul 19 22:32:20 myname-ThinkPad systemd[21308]: minecraft.service: Changing to the requested working directory failed: Permission denied
Jul 19 22:32:20 myname-ThinkPad systemd[21308]: minecraft.service: Failed at step CHDIR spawning /usr/bin/java: Permission denied

Jul 19 22:32:20 myname-ThinkPad systemd[1]: minecraft.service: Failed with result 'exit-code'.

I did deviate from the tutorial in a couple spots, and I’m sure that’s where the problem is. I used my own user profile to install the server instead of making a separate one, for a couple of reasons, but I made sure to change the paths accordingly. I also had to install Oracle Java, because OpenJDK was having issues installing the server file (I used 1.19 instead of 1.16, which is the one linked in the tutorial).

Here’s the systemd file:

[Unit]
Description=Minecraft Server
After=network.target

[Service]
User=myname
Nice=1
KillMode=none
SuccessExitStatus=0 1
ProtectHome=true
ProtectSystem=full
PrivateDevices=true
NoNewPrivileges=true
WorkingDirectory=/home/myname/mc_server/server
ExecStart=/usr/bin/java -Xmx1024M -Xms1024M -jar server.jar nogui
ExecStop=/home/myname/mc_server/tools/mcrcon/mcrcon -H 127.0.0.1 -P 25575 -p serverpasswd stop

[Install]
WantedBy=multi-user.target

So I guess my question is, is there any way to fix this without having to make a separate user profile or going back to OpenJDK (and by extension, an older version of the game)?
