composer 镜像问题

今天使用composer更新laravel-admin的版本,一直卡在下面这个阶段

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

实现已经使用了国内镜像,网友说还是镜像的问题,换成laravel的镜像果然就好了

composer config repo.packagist composer https://packagist.laravel-china.org
