php 在docker 中使用composer 报内存溢出的解决方法

Posted 2020-12-12 jackluo

最近 需要用到有盟的推送，不想自己写，准备在github上面找个来改改，本地用的环境是docker 镜像,然后在docker 中 composer 时的时候，报了一个错

 docker exec -it www /bin/bash

root@85c8ee9b5e27:/var/www/html/newyouchengdu# composer require lzg-xiyi/umengpush
Do not run Composer as root/super user! See https://getcomposer.org/root for details

这个很明显的内存溢出错，怎么办，肯定 是改不限制内存

然后找到了解决方案

root@85c8ee9b5e27:/var/www/html/newyouchengdu# php -d memory_limit=-1 /usr/local/bin/composer require lzg-xiyi/umengpush -vvv
