更换composer镜像源为阿里云

阅读更多关于更换composer镜像源为阿里云

说一说我为什么会更换镜像源，今天我准备给公司的项目添加一个 Excel 导出的功能，需要 PhpSpreadsheet 插件来实现我的功能。输入命令发现提示我 Authentication required (packagist.laravel-china.org): what？这是什么提示我需要用户名。不对啊平常都没有出现这个问题。我就去查百度了发现原来 laravel-china 的 package 镜像站将要停止运营了，这个消息并不是很好。用了很久的镜像站了，非常不错。哎，人家也坚持了两年已经很不错了。没办法我只能更换了。下面是我更换为阿里云镜像的操作步骤：官网： https://developer.aliyun.com/composer 全局替换 $ composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ $ composer clear-cache # 此步奏选泽性操作，清除所有 package 缓存。当前项目替换 $ cd 项目目录 $ composer config repo.packagist composer https://mirrors.aliyun.com/composer/ 来源： oschina 链接： https://my.oschina
