尝试设置HMR，但遇到此错误：

  

[HMR]更新检查失败：错误：清单请求   http://localhost:8080/bdfcd3cc99a34de2ac8c.hot-update.json超时。       在XMLHttpRequest.request.onreadystatechange

     

获取http://localhost:8080/bdfcd3cc99a34de2ac8c.hot-update.json网：: ERR_CONNECTION_REFUSED

我的webpack配置如下：

  output: {
    // path: path.resolve(ROOT_PATH,'dist'),publicPath: 'http://localhost:8080/',filename: '[name].bundle.js',chunkFilename: '[id].bundle.js'
  },mode: 'development',devtool: 'cheap-module-source-map',devserver: {
    allowedHosts: ['.ec2.pin220.com'],// 0.0.0.0 binds to all interfaces. The public port is 8080 which is served
    // by nginx and proxied to the internal webpack port of 10005.
    host: '0.0.0.0',port: 10005,hot: true,hotOnly: true,compress: true,headers: {
      'access-control-allow-origin': '*'
    }

Webpack输出如下：
