Javascript npm安装将react router从package-lock.json中删除

当我从我的应用程序中删除node_模块，然后运行npm install时，我的package-lock.json将被更改，react router将从中删除。我得到的错误是找不到模块react路由器。在它完美工作之前。这是我的网页配置：

`module.exports = {
  entry: ['whatwg-fetch', "./js/app.jsx"],
  output: { filename: "./js/out.js" },
  watch: true,
  devServer: {
  inline: true,
  contentBase: './',
  port: 3001
  },
  module: {
  loaders: [
      {
      test: /\.jsx$/, exclude: /node_modules/,
      loader: 'babel-loader',
      query: { presets: ['es2015', 'stage-2', 'react'] }
      },
      {
      test: /\.css$/,
      loader: 'style-loader!css-loader'
      }
    ]
  }
}`

还有我的package.json

    "test": "echo \"Error: no test specified\" && exit 1",

您很可能只是安装了

react-router-dom

，而没有将其添加到

依赖项中

，然后才删除

节点\ u模块

。尝试安装它并将其添加到您的

依赖项中

，它将再次工作

npm i -S react-router-dom

---

React路由器dom已卸载，因为您删除了节点\ U模块，因此必须重新安装React路由器

npm安装--保存路由器dom
