webpack-hot-middleware总是重新加载页面热重载不工作

Question

我查看了所有手册，但代码更改后仍然是我的应用刷新所有页面不热重新加载具体更改任何想法为什么？ webpack.config：

export default {
  debug: true,
  devtool: 'cheap-module-eval-source-map',
  entry: [
    './src/index',
    'webpack-hot-middleware/client?path=/__webpack_hmr&timeout=20000&reload=true', //note that it reloads the page if hot module reloading fails.
  ],
  target: 'web',
  output: {
    path: __dirname + '/dist', // Note: Physical files are only output by the production build task `npm run build`.
    publicPath: '/',
    filename: 'bundle.js'
  },
  externals: {
    "$": "jQuery"
  },
  devServer: {
    contentBase: './src'
  },
  plugins: [
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new webpack.ProvidePlugin({
      $: "jquery",
      jQuery: "jquery"
    })
  ],
  module: {
    loaders: [
      {test: /\.js$/, include: path.join(__dirname, 'src'), loaders: ['babel']},
      {test: /\.css/, loader: 'style-loader!css-loader!postcss-loader'},
      {test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: 'file'},
      {test: /\.(woff|woff2)$/, loader: 'url?prefix=font/&limit=5000'},
      {test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream'},
      {test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml'},
      {test: /\.(png|jpg)$/, loader: 'url?limit=250000'}
    ]
  },
  postcss: function () {
    return [precss, autoprefixer];
  }
};

index.js

app.use(webpackDevMiddleware(compiler, {
  noInfo: true,
  hot:true,
  publicPath: config.output.publicPath
}));


app.use(webpackHotMiddleware(compiler, {
  log: console.log,
  path: '/__webpack_hmr',
  heartbeat: 10 * 1000,
}));


app.use('/static',express.static(path.join(__dirname, '../src')));


app.get('*', function(req, res) {
  res.sendFile(path.join( __dirname, '../src/index.html'));
});

app.listen(port, function(err) {
  if (err) {
    console.log(err);
  }
});
