启动 React 时出错

  • 772

我运行 npm start 命令并收到以下错误：

MacBook-Pro-Kirill:crud-ui KirillBelyakov$ npm start

> crud-ui@0.1.0 start /Users/KirillBelyakov/crud-ui
> react-scripts start

sh: react-scripts: command not found

    可能有问题PATH：

    尝试全局安装。

    如果npm，那么：

    npm install -g react-scripts

    如果yarn，那么：

    yarn global react-scripts

    此外，作为一种选择，您可以尝试更改package.json，而不是"start": react-scripts start"编写：

    "start": "NODE_ENV=production node_modules/react-scripts/bin/react-scripts.js start"
