当webpack安装到现有的反应项目时，react-scripts start会抛出错误

安装webpack后运行 npm start 后，我的反应项目出错了 .

npm install webpack
npm install webpack-dev-server

这是我的package.json（没有上面的包）

{
  "name": "myproject",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-scripts": "0.9.3"
  },
  "dependencies": {
    "babel-core": "^6.24.1",
    "babel-loader": "^7.0.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "react-router": "^3.0.2"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

一旦我安装webpack和webpack-dev-server，我就开始在 npm start 上收到此错误

Failed to compile.

这是我的npm版本 .

$ npm -v
4.5.0

这与我的代码或npm / react-scripts的问题有什么关系？
