vs|Flutter Setup: Running pub upgrade.. Flutter Setup:Building flutter tool...

打开vs code后一直显示 Flutter Setup: Running pub upgrade..Flutter Setup:Building flutter tool...
flutter doctor也失败,提示:Building flutter tool... Running pub upgrade... 系统找不到指定的路径
太难了,随便一个报错都很难搜到o(╥﹏╥)o
解决办法:
【vs|Flutter Setup: Running pub upgrade.. Flutter Setup:Building flutter tool...】删除 flutter/bin 下的cache文件夹,然后再去 flutter doctor
