Raspberry Pi上のLaravelプロジェクトにcomposerでlaravel-corsを入れようとすると、次のようなエラーが出ました。
$ composer require fruitcake/laravel-cors
Using version ^1.0 for fruitcake/laravel-cors
./composer.json has been updated

Installation failed, reverting ./composer.json to its original content.
The following exception is caused by a lack of memory or swap, or not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details
PHP Warning: proc_open(): fork failed - Cannot allocate memory in phar:///usr/local/bin/composer/vendor/symfony/console/Application.php on line 952

[ErrorException]

解決方法
使ってなさそうなサービスなどをstopしてメモリを解放すれば解決すると思ったのですが、だめでした。swapを増やしてみると解決しました。
スワップの増やし方
$sudo vi /etc/dphys-swapfile
// CONF_SWAPSIZEを変更する
CONF_SWAPSIZE=1024
$sudo systemctl restart dphys-swapfile
再度、composerを実行すると正常にlaravel-corsがプロジェクトに追加されました。
