安装react-router-dom后，react不会启动

Question

我有新的反应，这是问题所在：

我的反应应用程序在我的Ubuntu机器上工作正常，直到我安装了qazxsw poi

react-router-dom

现在我不能再开始反应了：

npm i --save  react-router-dom

错误日志文件是这样的：

me@desktop:~/front-myapp$ npm start

> [email protected] start /home/me/front-myapp
> react-scripts start

sh: 1: react-scripts: not found
npm ERR! file sh
npm ERR! code ELIFECYCLE

npm ERR! syscall spawn

npm ERR! spawn ENOENT

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我怎样才能解决这个问题？

Answer 1

即使它很棘手：

1. {
     "name": "front-myapp",
     "version": "0.1.0",
     "private": true,
     "dependencies": {
       "react": "^16.4.2",
       "react-dom": "^16.4.2",
       "react-router": "^4.3.1",
       "react-router-dom": "^4.3.1",
       "react-scripts": "1.1.5"
     },
     "scripts": {
       "start": "react-scripts start",
       "build": "react-scripts build",
       "test": "react-scripts test --env=jsdom",
       "eject": "react-scripts eject"
     }
   }

2. rm -rf node_modules

应该做的伎俩。

npm install是一个有点麻烦的包，所以很可能，它已被从react-scripts文件夹中删除
