Authentication required (packagist.laravel-china.org)

这类问题，先搜素一下社区然后再发帖可好。你看看这儿。
Wiki：Laravel 安装和开发环境：修改项目依赖为新的镜像地址

@oyghan 感谢回复，我的问题貌似不是这个。
我执行

composer update nothing
composer update --lock

以下是我的配置：

@oyghan 我有按照
博客：Composer 镜像限额，出现要求用户名认证时请使用替代源 这篇文章处理，但是问题依然存在

博客：Laravel China 镜像完成历史使命，将于两个月后停用

Laravel China 镜像完成历史使命，请使用阿里云镜像：https://mirrors.aliyun.com/

切换源之后，还是提示输出账号密码

已解决。

，是我在框架的composer.json里写死了源。
