【问题描述】：

我有一个 react-redux 应用程序运行良好，每次文件更改后 UI 都会自动更新，然后我决定将 sass 插入我的应用程序并且自动重新加载停止工作。所以为了在我的应用程序中获得 sass，我必须安装 sass-loader、node-sass、css-loader 等。但是其中一个加载器需要 webpack 2，所以我从 1.15 切换到 2.0，现在当我运行“ npm run dev" 每次文件更改后我都会看到 webpack 重新编译，但我的 UI 没有在浏览器中自动重新加载。谁能帮我解决这个问题？

这是我的 webpack 配置文件：

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');
var path = require('path');

module.exports = 
  context: path.join(__dirname, "src"),
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/app.js",
  module: 
    loaders: [
      
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: 
          presets: ['react', 'es2015', 'stage-0'],
          plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy', "transform-object-rest-spread"],
        
      ,
      
        test: /\.scss$/,
        loader: 'style-loader!css-loader!sass-loader'
      
    ]
  ,
  output: 
    path: __dirname + "/src/",
    filename: "app.min.js"
  ,
  plugins: debug ? [] : [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin( mangle: false, sourcemap: false ),
  ],
;

这是我的 package.json 文件：

  "version": "0.0.0",
  "description": "Code challenge from MediaMath",

【参考方案1】：

看起来问题出在使用 webpack-dev-server 上。当我使用版本 2.0.0 而不是 1.14.1 时，它再次开始自动重新加载。
