javascript - npm install 从 package-lock.json 中移除 react 路由器

问题描述

当我从我的应用程序中删除 node_modules，然后运行 ​​npm install 时，我的 package-lock.json 被更改并且 react-router 被从中删除。我收到未找到模块 react-router 的错误。在它完美运行之前。这是我的 webpack 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'
      }
    ]
  }
}`

和我的 package.json

  "version": "1.0.0",
  "description": "test",
  "main": "webpack.config.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "./node_modules/.bin/webpack-dev-server --hot"
  },

解决方案

您很可能只是react-router-dom在dependencies删除node_modules. 尝试安装它并将其添加到您的dependencies.，它会再次工作。

npm i -S react-router-dom
