我正在尝试将Flutter的频道切换为使用Flutter Web。但是每次我遇到这个错误。既不转换为Flutter master也不转换为Flutter beta。

P:\FlutterProjects>flutter channel master
Switching to flutter channel 'master'...
git: From https://github.com/flutter/flutter

在命令行中,导航到安装flutter的目录,然后运行以下命令

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

如果上述方法无效,请尝试以下操作

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

上面的命令将删除断开的引用,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抖动。

$ flutter upgrade
$ flutter channel master
$ flutter upgrade
