提前感谢大家。

在您的webpack.confg.js中，您有以下内容：

module.exports = {
  devtool: 'eval',
  entry: [
    'webpack-dev-server/client?http://localhost:9000',
    'webpack/hot/only-dev-server',
    './src/index' // <-- no src dir in project
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    // new webpack.NoEmitOnErrorsPlugin()
  ],
  resolve: {
    extensions: ['.js', '.jsx']
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        include: [path.join(__dirname, 'src')], // <-- no src dir in project
      },
      {
        use: [
          {
            loader: 'react-hot-loader'
          },
          {
            loader: 'babel-loader',
            options: {
              // cacheDirectory: 'babel_cache',
              presets: ['react', 'es2015']
            }
          }
        ]
      }
    ]

  }
};

经过测试，在我的本地电脑上运行。

找到了解决方案。在规则
部分，我犯了一些错误。以下是正确的规则

rules: [{
  test: /\.jsx?$/,
  include: [path.join(__dirname, 'src/')],
  use: [
    {
      loader: 'react-hot-loader'
    },
    {
      loader: 'babel-loader',
    }
  ]
}]

这将是正确的webpack.config.js

var path = require('path');
var webpack = require('webpack');

module.exports = {
  devtool: 'eval',
  entry: [
    'webpack-dev-server/client?http://localhost:9000',
    'webpack/hot/only-dev-server',
    path.resolve(__dirname, 'src/')
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin()
  ],
  resolve: {
    extensions: ['.js', '.jsx']
  },
  module: {
    rules: [{
      test: /\.jsx?$/,
      include: [path.join(__dirname, 'src/')],
      use: [
        {
          loader: 'react-hot-loader'
        },
        {
          loader: 'babel-loader',
        }
      ]
    }]
  }
};

感谢大家的帮助。

JS控制台中是否有错误？或者您在编译期间以及运行时都没有任何错误？请打开控制台并检查是否有任何错误。这将为您指明正确的方向。@saadq控制台上没有错误。@AndrewLi已经发布了代码并给出了要点链接。
