Reactjs 问题开始反应

我在windows上运行ubuntu shell，当我尝试“npm启动”时，我得到了这个错误。还有其他人有这个问题吗

Starting the development server...

你在Windows上吗

您可能没有系统路径环境变量。请尝试在终端中运行此命令，然后再次运行该命令

export PATH=$PATH:C:\Windows\System32

这实际上是做什么的？你有可以分享的链接吗？我可以读到吗？另外，我尝试了一些奇怪的方法，现在效果不错。在项目文件中，我将react脚本更改为2.1.8版，之前是3.1.1版。然后，我还运行了npm安装来处理依赖项，它工作了。。。
