composer
一篇不错的文章
一、安装和使用
1.1 安装

1.2 镜像切换
# 全局切换国内镜像 # 阿里云 composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ # 中国全量镜像 composer config -g repo.packagist composer https://packagist.phpcomposer.com # 取消全局配置 composer config -g --unset repos.packagist # 当前工程切换配置 composer config repo.packagist composer https://mirrors.aliyun.com/composer/ # 取消当前工程配置 composer config --unset repos.packagist # 清除缓存 composer clear
1.3 基本使用
# 安装依赖包 composer install # 安装依赖 composer require monolog/monolog # 更新所有依赖 composer update # 移除一个包及其依赖 composer remove monolog/monolog # 列出所有已经安装的包 composer show
二、问题及解决
2.1 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('memory_limit').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
2.2 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",
