查看、修改内存限制

代码语言：javascript复制
php -r "echo ini_get('memory_limit');"

php -r "phpinfo();" | grep memory
代码语言：javascript复制
memory_limit = 1024M;
代码语言：javascript复制
// 临时设置最大内存占用
ini_set('memory_limit', '1024M');
// 设置脚本最大执行时间为 0 永不过期
set_time_limit(0);

忽略 php 版本限制

这个是极不推荐的，这样会造成库安装的版本错误。不应该使用。

代码语言：javascript复制
composer require hellogerard/jobby --ignore-platform-reqs

推荐做法：

代码语言：javascript复制
which composer
# /usr/local/bin/composer

{正确的 PHP 版本}/bin/php /usr/local/bin/composer require hellogerard/jobby

/usr/local/opt/php@7.1/bin/php -d memory_limit=-1 /usr/local/bin/composer update -vvv

emory-limit-errors for more info on how to handle out of memory errors

代码语言：javascript复制
php -d memory_limit=-1 /usr/local/bin/composer update

更新 composer.lock

若项目之前已通过其他源安装，则需要更新 composer.lock 文件：

代码语言：javascript复制
composer update --lock

homebrew PHP

php composer https code 内存
