我用composer下载Notification，提示没有这个插件，估计是我把Notification拼错了，
命令用的是
composer require illuminate/Notification
提示的错误是[InvalidArgumentException]
Could not find package illuminate/Notification at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability
请大神帮助解决一下，谢谢!(注:我的路径我不确定对不对，请大神帮助一块解决吧)
