composer require で Allowed memory size が発生したときの対処方法

はじめに

composer require を行ったときに Allowed memory size が発生したので対処方法をまとめました

環境

$ sw_vers
ProductName:    macOS
ProductVersion: 11.2.2
BuildVersion:   20D80

$ php -v
PHP 7.4.9 (cli) (built: Aug  8 2020 11:29:07) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.9, Copyright (c), by Zend Technologies
    with Xdebug v2.9.6, Copyright (c) 2002-2020, by Derick Rethans

$ php artisan -V
Laravel Framework 8.31.0

解決した方法

COMPOSER_MEMORY_LIMIT=-1 でメモリ制限を解除して composer require を実行することで解決しました

以下のように実行すると、メモリ不足となりました

$ composer require laravel/ui
Using version ^3.2 for laravel/ui
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted

そこで、 COMPOSER_MEMORY_LIMIT=-1 の環境変数を渡して、 composer require を実行することでメモリ不足を回避しました

$ COMPOSER_MEMORY_LIMIT=-1 composer require laravel/ui
Using version ^3.2 for laravel/ui
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
