I'm on Linode 1G RAM basic plan. Trying to install a package via Composer and it's not letting me. My memory limit is set to "-1" on PHP.ini

推荐答案

有点老了，但以防万一新人正在寻找解决方案，更新您的 PHP 版本可以解决问题.

A bit old but just in case someone new is looking for a solution, updating your PHP version can fix the issue.

您还应该提交您的 composer.lock 文件并在资源密集型较少的生产环境中安装 composer.

Also you should be committing your composer.lock file and doing a composer install on a production environment which is less resource intensive.
