Composer hanging while updating dependencies

Question

I tried updating a Laravel project I'm working on today using composer update

But it hung on Updating dependencies (including require-dev)

So I tried things like updating composer, dump-autoload, but nothing seemed to work. Then I ran it in verbose mode: composer update -vvv

And I noticed it hung while reading this json:

Reading path/to/Composer/repo/https---packagist.org/provider-cordoval$hamcrest-php.json from cache

I tried searching for cordoval/hamcrest-php on packagist.org and couldn't find it. This isn't listed as a dependency in my composer.json

Searching through my vendor folder, I notice the mockery/mockery package I use requires hamcrest/hamcrest-php, but I can't find anything that makes any reference to cordoval.

Any idea what's wrong and how I can fix it so that I can do the update?

Here's my composer.json:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {
        "laravel/framework": "4.2.*",
        "iron-io/iron_mq": "dev-master",
        "phpunit/phpunit": "4.2.*",
        "mockery/mockery": "dev-master",
        "xethron/migrations-generator": "dev-master",
        "mailgun/mailgun-php": "dev-master"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable"
}

Update

I've tried removing some of the packages from my composer.json, including the "mockery/mockery" package. The only change it made was that Composer would hang on a different file.

After leaving Composer running like that for quite a long time, it finally exited with an error such as the following:

/path/to/ComposerSetup/bin/composer: line 18:  1356 Segmentation fault      php "${dir}/composer.phar" $*

Not sure what to do about that...

Answer 1

So it turns out the problem was with php's xdebug extension. After disabling it in my php.ini, composer ran without any problems.

And just to note, the hang-up wasn't actually occurring while reading files from the cache. It was the step right after where composer was trying to resolve dependencies. It just never finished that step and never printed the output. That's why no matter what I did, it always appeared to be stuck reading a file from the cache.

Answer 2

1st of all : Check firewall and proxy connections. If everything is ok but composer is still hanging try to clear composer cache:

composer clear-cache

https://getcomposer.org/doc/03-cli.md#clear-cache

2nd option If these steps does not repair your composer then it's possible that the system does not have enough RAM memory available (I faced this problem and the symptomps were the same that you describe). At this point you have two options:

a) Increase memory (Virtual Machines or Docker) : Your container or VM needs more available memory. Follow this guide: https://stackoverflow.com/a/44533437/3518053

b) Generate swap file (Linux) : Try creating a swap file to provide more memory: (Above commands are from composer killed while updating)

free -m
mkdir -p /var/_swap_
cd /var/_swap_
#Here, 1M * 2000 ~= 2GB of swap memory
dd if=/dev/zero of=swapfile bs=1M count=2000
mkswap swapfile
swapon swapfile
chmod 600 swapfile
echo "/var/_swap_/swapfile none swap sw 0 0" >> /etc/fstab
#cat /proc/meminfo
free -m

Answer 3

Restart your system.

I faced the same problem today. Going by advice, turned off xdebug, but did not help. Verified all files were present. Restarted my system, and it worked.

Answer 4

Check if you are running the minimum required php version

Compare with the specified required php version in the composer.json file

Open terminal run

php -v

Cross check in composer.json file see example below

"require": { "php": "^7.1.3", }

Answer 5

check the path of [xdebug] zend_extension = "file/path" in php.ini

Answer 6

Working for me. First Run command for auto load, then clear cache and run update.

composer dump-autoload
php artisan cache:clear
php artisan view:clear
update composer
