composer的一些报错及解决办法

问题1

执行以下命令：

composer require sonata-project/doctrine-orm-admin-bundle "2.3.*"

报错：

PHP Fatal error:  Allowed memory size of 1610612736 bytes exhausted (tried to allocate 32 bytes)

解决：

php -r "echo ini_get(&＃39;memory_limit&＃39;).PHP_EOL;"  # 查看memory大小
COMPOSER_MEMORY_LIMIT=-1 composer require sonata-project/doctrine-orm-admin-bundle  # 临时设置memory大小

参看官方说明（打开太慢了）：

https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors

问题2

but these conflict with your requirements or minimum-stability.

解决：在composer.json中添加以下

"minimum-stability": "dev",

切换composer国内镜像

composer config -g repo.packagist composer https://packagist.phpcomposer.com
