Composer doesn't see all installed PHP extensions

[mnabialek]

I'm using Docker and have installed GD in recommended way as showed in official PHP Docker repository. My Dockerfile looks like this:

When I run:

php -m

I'm getting:

There's no GD here, so when I try to install for example barryvdh/laravel-dompdf I'm getting following error:

Problem 1
    - dompdf/dompdf v0.7.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - dompdf/dompdf v0.7.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - dompdf/dompdf v0.7.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - Installation request for dompdf/dompdf (locked at v0.7.0) -> satisfiable by dompdf/dompdf[v0.7.0].

The only way to install it is using --ignore-platform-reqs parameter but I need to use it each time and obviously it doesn't solve issue when my virtual machine misses some libs that are required and not installed.

Also when I run:

php -r 'print_r(get_loaded_extensions()); foreach (get_loaded_extensions() as $ext) echo $ext." ".phpversion($ext)."\n";'

in console I'm getting something like this:

For some extensions version is missing but for example for ctype it's missing but it's available in output of composer show -p and gd is not there at all.

I've already seen https://github.com/composer/composer/issues/4353 but it's not solving the issue. The question is - what's the reason that composer doesn't see GD extension? What's the way composer finds what extensions are available in system? Or maybe official way of installing GD is broken and it should be installed somehow else?

The strange thing is that GD is working without a problem after such installation, the only issue is that Composer doesn't see it.

I'm using Composer version 1.2.1 2016-09-12 11:27:19

Can you share some more about your docker setup? Does everything use the same container?

[mnabialek]

No, I'm using 3 containers - one for PHP, one for webserver and one for database. My docker-compose looks like this and I'm using for the whole setup the code I've put on github. The same problem is for both PHP 5.6 installation and for PHP 7.

[alcohol]

I think you are using the image that extends ubuntu stuff. It could be their fpm image has a separate php ini for fpm and cli. Did you try running php --ini ?

[mnabialek]

When I run php --ini I'm getting:

Configuration File (php.ini) Path: /usr/local/etc/php
Loaded Configuration File:         /usr/local/etc/php/php.ini
Scan for additional .ini files in: /usr/local/etc/php/conf.d

Content of /usr/local/etc/php/php.ini is:

max_execution_time = 180
memory_limit = 1024M

post_max_size = 40M

and content of /usr/local/etc/php/conf.d/20-gd.ini is:

; configuration for php gd module
; priority=20
extension=gd.so

[alcohol]

Can you show me how you run the command + output, both for php -m and composer show -p ?

[mnabialek]

Exactly like this (I login via putty to PHP container) and:

Just in case when I run php -i the part about GD looks like this:

ftp

gd

gd.jpeg_ignore_warning => 0 => 0

[alcohol]

Can you run and share the output of

composer show -p
cat /tmp/*-php.ini

# replace <part> with the partial filename of the only file ending with -php.ini inside /tmp
php -c /tmp/<part>-php.ini -m

[stof]

Can you past the output of this command too ?

php -r "echo (new ReflectionExtension('gd'))->getVersion();"

[mnabialek]

@alcohol I don't have any .ini files in /tmp directory, I have ini files only in directories I showed yesterday:

$php --ini
Configuration File (php.ini) Path: /usr/local/etc/php
Loaded Configuration File:         /usr/local/etc/php/php.ini
Scan for additional .ini files in: /usr/local/etc/php/conf.d

/usr/local/etc/php/conf.d/20-pdo_mysql.ini,
/usr/local/etc/php/conf.d/20-xdebug.ini

@stof The result of command is as below:

root@somesite.app:/usr/share/nginx/html$php -r "echo (new ReflectionExtension('gd'))->getVersion();"
root@somesite.app:/usr/share/nginx/html$

[mnabialek]

@alcohol Any update on this?

[alcohol]

I have no way to reproduce this, so, no.

But I can say with high confidence that this is probably related with the way you've setup your docker images. Also, the output of that php -r command shows that gd was not available in that container.

[maryo]

I have the same problem on Windows. I've recently added 3 extension dependencies to composer.json primarily because of APCu.

It works fine on Linux dockerized CI server though.
php -m contains on my Windows machine:

fileinfo
gd
apcu
...

composer show -p does not and composer update complains:

Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - The requested PHP extension ext-gd * is missing from your system. Install or enable PHP's gd extension.
  Problem 2
    - The requested PHP extension ext-fileinfo * is missing from your system. Install or enable PHP's fileinfo extension.
  Problem 3
    - The requested PHP extension ext-apcu * is missing from your system. Install or enable PHP's apcu extension.

php -r "echo (new ReflectionExtension('gd'))->getVersion();"
7.0.6

[alcohol]

@maryo unless you show us the full output of the following commands run on your windows local host, we cannot help you:

php --version
php -m
composer show --platform

Please also include the lines that show how you run the command and in what directory you run the command. Do not hide anything that you might think is irrelevant, because it most likely is relevant.

[maryo]

@RobLoach Sorry for taking your time. My fault. I forgot I created a batch file running composer with only some extensions enabled because of xdebug few years ago. How silly.
@php -n -d extension=ext\php_openssl.dll -d extension=ext\php_mbstring.dll -d extension=ext\php_curl.dll "%~dp0composer.phar" %*

[mnabialek]

@alcohol @maryo I had exact same problem. I've created alias like this:

alias composer="php -n /usr/local/bin/composer"

to not load Xdebug (but obviously all other extensions) and that's why Composer didn't see GD2 extension when installing packages.

Sorry for reporting. It was obviously not Composer fault but mine.

[Seldaek]

Note that latest composer (1.3+) disables xdebug automatically so you don't need to do such hacks like running it via php -n anymore.

[mnabialek]

@Seldaek Didn't know about it. Thanks for sharing

[david-cefr]

In case this could help :

I ran into the same issue, I was running PHP locally with GD and composer thru a docker container.
the command composer show -p would not show "ext-gd".

To solve the problem, I've installed Composer locally and now it runs fine.
Another solution would've been to install GD on the Composer container.
