为什么我的VS代码终端无法识别“颤振”一词？

Question

我正在运行一个flutter devices的命令来检查已连接的设备，但是它给出了以下错误：

flutter: The term 'flutter' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of 
the name, or if a path was included, verify that the path is correct and try again.

flutter devices

Answer 1

在VS代码中进行批量下载，路径变量设置和“ flutter”启用活动之后，您可能会忘记重新启动已经打开的VS代码。因此重新启动VS代码

Answer 2

u必须添加路径变量，例如C：\ Program Files \ flutter \ bin，然后重新启动Visual Code。现在您可以在终端上运行命令了。
