Webpack在运行webpack命令时出错

Question

我得到了以下错误：

[HMR] Waiting for update signal from WDS...

当我在终点站跑"webpack“的时候

我的webpack配置js文件如下：

var webpack = require('webpack');

module.exports = {
    entry: [
        'webpack-dev-server/client?http://localhost:8080',
        'webpack/hot/only-dev-server',
        './src/index.js'
    ],
    module: {
        loaders: [{
            test: /\.js?$/,
            exclude: /node_modules/,
            loader: 'react-hot!babel'
        }]
    },
    resolve: {
        extensions: ['', '.js']
    },
    output: {
        path: 'dist',
        publicPath: '/',
        filename: 'bundle.js'
    },
    devServer: {
        contentBase: './dist',
        hot: true
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
};

我的package.json如下：

{
  "name": "hwr",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "babel": {
    "presets": [
      "es2015",
      "react"
    ]
  },
  "devDependencies": {
    "babel-core": "^6.11.4",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1",
    "react-hot-loader": "^1.3.0",
    "webpack": "^1.13.1",
    "webpack-dev-server": "^1.14.1"
  },
  "dependencies": {
    "history": "^3.0.0",
    "react": "^15.3.0",
    "react-dom": "^15.3.0",
    "react-router": "^2.6.1"
  }
}

这个错误从何而来？

这不是一个错误，您启用了在Webpack构建中的热模块替换(因此HMR)功能。这只是来自HMR功能的日志消息之一。听起来你不想打开HMR？在这种情况下，您应该从入口点、'webpack-dev-server/client?http://localhost:8080', 'webpack/hot/only-dev-server'加载程序和加载器条目、从插件中删除new webpack.HotModuleReplacementPlugin()和从new webpack.HotModuleReplacementPlugin()服务器设置中删除hot: true条目。
