镜像配置
在进行install/update的时候，迟迟没有加载出资源，这时候需要看一下镜像，进行更换镜像地址
全局配置
所有项目都会使用该镜像地址
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
取消配置
composer config -g --unset repos.packagist
项目配置
仅修改当前工程配置，仅当前工程可使用该镜像地址
composer config repo.packagist composer https://mirrors.aliyun.com/composer/
取消配置
composer config --unset repos.packagist
安装项目
安装
#如有composer.lock 文件,直接安装. 否则从composer.json 安装最新扩展包和依赖,并生成composer.lock文件
composer install
#从composer.json 安装最新扩展包和依赖, 如果没有指定具体的包配置，composer.json中全部配置进行更新
composer update
#从composer.json修改对应包的配置 或者 命令后跟对应包的配置,并更新到最新
composer update vendor/package
#添加安装 new/package
composer require new/package
#可以指定版本
composer require new/package ~2.5.
调试
composer 命令增加-vvv 可输出详细的信息，命令如下
composer -vvv require new/package
遇到的问题？
建议将composer版本更新到最新版本
composer self-update
执行诊断命令
composer diagnose
清除缓存
composer clear
若项目之前已通过其他源安装，则需要更新 composer.lock 文件，执行命令
composer update --lock
