Git 颤振能'；t将频道切换到beta

我正在尝试切换颤振通道以使用颤振web。但每次我都会犯这个错误。无论是切换到颤振主控还是颤振测试

P:\FlutterProjects>flutter channel master
Switching to flutter channel 'master'...
git: From https://github.com/flutter/flutter
git:    1ad9baa8b..8af6b2f03  stable         -> origin/stable

在命令行中，导航到安装颤振的目录并运行以下命令

$ rm .git/refs/remotes/origin/beta
$ git fetch

如果上述方法不起作用，请尝试以下方法

$ git gc --prune=now
$ git remote prune origin

上面的命令将删除断开的参考，下面的命令将确保在更改通道之前在当前通道上完全升级颤振

$ flutter upgrade
$ flutter channel master
$ flutter upgrade

谢谢你的精彩回答，但我很抱歉地告诉你，它不起作用，我试图自己从目录中删除beta版，但git fetch仍然显示相同的错误/Hey@Prateek，我只是用更多可以尝试的命令更新了答案
