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 Using version ^1.0 for lzg-xiyi/umengpush ./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 (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52 Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52
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
