composer安装

例1：修改 composer 的全局配置文件

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

更换国内源，每个用户单独换源，才有效。

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

例2：修改当前项目的 composer.json 配置文件：

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