npm安装后npm启动失败

Question

我创建了一个示例项目(我的操作系统:Windows 10);

expo init test
cd test
npm start

一切运作良好,我可以在手机上看到我的应用程序和我的package.json看起来;

{
  "name": "empty-project-template",
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "expo": "^30.0.1",
    "react": "16.3.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-30.0.0.tar.gz",
  }
}

但是,如果我想安装像"uuid"这样的软件包;

npm install uuid

包安装没有问题,然后我写;

   npm start

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

我按'Y',但它给出了错误;

This command requires Expo CLI.
Do you want to install it globally [Y/n]? y
Installing the package 'expo-cli'...
events.js:183
      throw er; // Unhandled 'error' event
      ^

包名称并不重要,如果我安装任何包并运行npm start,我的项目已关闭,我无法使用我的项目,我测试了这一步yarn,同样的npm,我的错误是什么？

对于那些在这个问题上挣扎的人,

1. 导航到代码库的node_modules> .bin
2. 在该目录中查找expo和expo.cmd
3. 将它重命名为任何东西.

你已准备好出发.
