如何修改鏡像源
可以使用阿里巴巴提供的 Composer 全量鏡像 https://mirrors.aliyun.com/composer/
a). 配置只在當前項目生效
composer config repo.packagist composer https://mirrors.aliyun.com/composer/
# 取消當前項目配置
composer config --unset repos.packagist
b). 配置全局生效
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
# 取消全局配置
composer config -g --unset repos.packagist
