Question

当我的应用突然停止工作时，我只是在使用expo开发本机应用。

当我尝试重新启动应用程序时，好像expo已从计算机中删除，因为在运行expo start时收到错误消息：

'expo' is not recognized as an internal or external command,
operable program or batch file.

然后当我运行npm install

它似乎确实完成了最后的说明

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.7: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

audited 14262 packages in 23.291s

  run `npm audit fix` to fix them, or `npm audit` for details

但是当我运行Npm start

我被问到一个问题：

This command requires Expo CLI.
Do you want to install it globally [Y/n]?

我回复Y

然后回复：

      throw er; // Unhandled 'error' event
      ^

我尝试删除package-lock.json文件并运行npm install

我尝试删除Node_module文件夹并运行npm install

我都尝试过并运行npm install

什么原因导致此错误？我该如何解决？

**我期望什么？ **

奇怪的是，我发现一则帖子说，重启笔记本电脑并运行expo cli install命令后，重启笔记本电脑会有所帮助
