This solved my issues

or newer version (* = your php version )

Have tried for many times, the above answers don’t solve my quesiton, but this command helped me:

ubuntu users try this

this is work for php 7.2 but you can change this 7.2 to 5.2 and run this command it is work.

When I went to create a laravel project, I got this problem.

After googling, I got this solution.

I followed these steps:

Step 2: sudo apt-get install php7.2-intl

Step 3: sudo apt-get install php7.2-xsl

Step 4: sudo apt-get install php7.2-mbstring

this command would do the trick

After that, it is installing as it should.

Install according to your php-version.

since i have php7, I will do the following to list the php packages:
sudo apt-cache search php7-*

now to install packages run the following command with your desired package

UPDATE: Don’t forget to restart apache/

This was the fix for me when trying to install Laravel on a fresh WSL installation:

sudo apt-get install php7.2-gd

sudo apt-get install php7.2-intl

sudo apt-get install php7.2-xsl

sudo apt-get install php7.2-zip

On Ubuntu 16.04 php7 is now the default, so if you follow the top answers and are still having this issue, check your php version.

If your default php version is php7, but you followed an answer using php5 packages, you can use the following command to set the default version of php to php5.6:

Updated. For ubuntu users

The exact name of the extension depends on the repository from which you got PHP but look here. For example on CentOS:

I used below to fix issue

Gonna post this answer here after seeing some of the answers (including the accepted one) which claim to «do the trick». First, we need to identify the issue before fixing it.

the requested PHP extension gd is missing from your system.

As the above line clearly states, we need to install the extension php-gd.

How to explain Composer’s error log?

I did a lot of research on the web, but did not find a documentation of the composer error log. In the discussions I found, nobody had an explanation that was consistent with the error log. For example:

I know, what composer does and can resolve issues on my own, but I often have to consult packagist.org for this. Despite being quite (and unnecessarily) verbose, the composer log only gives me some hints. It does not really point out the concrete problems.

Does anyone know of a complete documentation or how to explain the reasoning behind the logs, maybe taking the above ones as an example?

1 Answer 1

Documentation of Composer can be found at getcomposer.org/doc, especially Troubleshooting section. Usually the dependency problems comes from misconfiguration of your composer.json and understanding Composer logs comes with experience or learning on trial and error. Documenting every possible errors out of hundreds can become quickly outdated. If you believe some specific error isn’t clear enough, you can always raise a new suggestion at the Composer’s GitHub page.

Errors

Here is a small guide explaining the common Composer’s errors:

Can only install one of: org/package[x.y.z, X.Y.Z].

If you see this messages, that could be the main cause of the dependency issue. It basically means that based on the Composer’s dependency calculation both of these versions are required, but only one major version can be installed (you cannot have both x.y.z and X.Y.Z, unless you split your configuration for different folders). To see why these packages are required, use the composer why / depends command and adjust the dependencies accordingly.

Installation request for org/package2 (locked at vX.Y.Z)

This message means that there was an installation request for org/package, however, it is locked at X.Y.Z. If the requested version is not compatible with the locked version (like a different major version), you cannot install both. This message often comes along with already mentioned «Can only install one» one. So, whenever you see «locked at», that means Composer reads your installed package version from the composer.lock file. To troubleshoot, you can use composer why / depends command to find why the package was requested and adjust the compatibility, otherwise, you may try to remove composer.lock file and start from scratch (ideally from the empty folder).

org/package1 vx.y.z conflicts with org/package2[vX.Y.Z].

conflict with your requirements or minimum-stability

This message means as it reads, so you should check the required version and/or your minimum-stability settings.

This can be caused by a package being marked as non-stable and your requirements being «stable only. See: But these conflict with your requirements or minimum-stability

For any other errors, check out the official Composer’s Troubleshooting page.

Вопрос №29722 от пользователя Алексей Видякин в уроке «Исполняемые файлы в пакетах», курс «PHP: Настройка окружения»

Не могу установить опубликованный пакет глобально. Вот ошибка:

Сергей К., Да, по команде composer документация выводится. Попробую установить утилиту phploc получаю вывод:

(тут я сократил текст, т.к. он не многим отличается от первого спойлера)

Посмотрите топики с похожей проблемой тут и тут. Каким способом вы устанавливали composer?

Сергей К., Прошу прощения за задержку с ответом, но для решения проблемы я всё же поставил рядом ещё одну операционку, в ней я провожу эксперимент только по этой теме и ничего лишнего.

Способов установки composer было несколько. Установка с помощью официального руководства прошла безуспешно. Наверно потому что банально плохо владею английским, а перевод переводчиком мне дал абро катабру. Для меня во всяком случае перевод текста оказался связанным, но информативно бесполезен т.к. не точен. И те команды что я вводил понимал на 50% максимум. В итоге я получил тоже, что имею сейчас (ошибки см. выше)

Сергей К., Проблема решена.

Тогда я переключился на php, прогуглив проблему в этом ключе, как раз и пришёл к расширениям пакета, на которые я честно говоря внимания не заострял при установке composera (php-curl php-mbstring. ).

Алексей Видякин, Спасибо за публикацию! Ваш способ: sudo apt-get install php-xml помог мне справиться с такой же проблемой, с которой Вы столкнулись.

I have installed php7, I did the following to solve exactly the same error

If you are working in PHP version 5.* then you have to install

And if you are working in PHP version 7.* then you have to install

And if you are working in PHP version 7.2 then you have to install

Open your php.ini and uncomment this line:

It may not be enabled for php-cli, you can enable like this;

I guess, you are using ppa:ondrej php package (5.6), which is confusing you with default ubuntu 14.04 php package (5.5.9).

To install php 5.6 gd library from ppa:ondrej, you should use:

PHP 7.4.2 (cli) (built: Feb 5 2020 16:50:21) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.2, Copyright (c), by Zend Technologies

if you are working in PHP version 7.2 then you have to install

Before installing the missing dependency, you need to check which version of PHP is installed on your system.

In this case it’s php7.2. apt search php7.2 returns all the available PHP extensions.

You can now proceed to installing the missing dependency by running:

sudo apt install php7.2-gd

For php-8, just locate your php.ini file and uncomment the line extension=gd
Below is a picture guide for those using Xampp and Windows

Step 1: Open php.ini or locate it in your machine (C:/xampp/php/php.ini)

Step 2: Uncomment the line extension=gd by removing the semicolon

Step 3: Save your file and restart your services
