composer使用国内镜像还是很慢？

composer 下载包时，尽管已经更换为国内镜像了https://packagist.phpcomposer.com,但是还是会报错

Content-Length mismatch, received 32372 bytes out of the expected 480707 
https://packagist.phpcomposer.com could not be fully loaded, package information was loaded from the local cache and may be out of date

还是会很慢！！！！

解决办法

1、清除缓存

composer clear-cache

2、如果还是慢，更换为阿里镜像
地址：https://mirrors.aliyun.com/composer/
全局配置

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

取消配置

composer config -g --unset repos.packagist

当前项目配置

composer config repo.packagist composer https://mirrors.aliyun.com/composer/

取消配置

composer config --unset repos.packagist
