npm start on new create-react-app build返回ELIFECYCLE错误

Question

使用create-react-app创建了一个新的反应应用程序，现在在运行npm start时在终端中收到以下错误：

> react-scripts start

Attempting to bind to HOST environment variable: x86_64-apple-darwin13.4.0
If this was unintentional, check that you haven't mistakenly set it in your shell.


events.js:167
      throw er; // Unhandled 'error' event
  ^

尝试删除node-module文件夹和npm install。

Answer 1

在终端输入unset HOST。它将解决这个问题。

Answer 2

我能够通过运行npm install create-react-app而不是npm install -g create-react-app来修复类似的错误。希望能帮助到你。

Answer 3

你应该创建.env文件

在Create React App中阅读此环境
