无法使用npm start命令启动React应用

Question

我正在尝试运行我的react-ebay-clone，但是

npm start

命令不起作用。相反，反应会引发此错误

freduah@freduah:~/react-ebay-clone/react-ebay-clone$ npm start

> react-ebay-clone@0.1.0 start /home/freduah/react-ebay-clone/react-ebay-clone
> react-scripts start

sh: 1: react-scripts: not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! react-ebay-clone@0.1.0 start: `react-scripts start`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the react-ebay-clone@0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

freduah@freduah:~/react-ebay-clone/react-ebay-clone$ 

下面是我的package.json文件

  "version": "0.1.0",

  "dependencies": {

}

我发现了以前的堆栈溢出

npm start error with create-react-app。
