Last updated at Posted at 2020-07-24

環境

  • PHP 7.4.5
  • Composer 1.10.5

事象

composer requireしようとしたら、メモリ確保できやんでと怒られた。
https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors を見ろと言われているので、それに従う。


$ composer require --dev nunomaduro/larastan
Using version ^0.6.1 for nunomaduro/larastan

PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 223

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 223

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

手順

※下記の手順は、PHP全体のメモリ上限値を無制限に変更しています。
 環境変数COMPOSER_MEMORY_LIMIT=-1を設定し、Composerのメモリ上限値のみ変更することを推奨いたします。
 (詳細はこちらを参照してください)

# memory_limitの設定値を確認
$ php -r "echo ini_get('memory_limit').PHP_EOL;"
128M

# php.iniの場所を確認
$ php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/etc/php/7.4
Loaded Configuration File => /usr/local/etc/php/7.4/php.ini

# memory_limitの設定値を更新
$ vi /usr/local/etc/php/7.4/php.ini
memory_limit = 128M
↓
memory_limit = -1

# memory_limitの設定値を確認
$ php -r "echo ini_get('memory_limit').PHP_EOL;"
-1
