反应代码拆分：ChunkLoadError：加载块0失败

我正在尝试将代码拆分引入我的项目，但是我无法使其正常工作。我得到的错误是：

我有一个monorepo设置，其中的lib/工作区包含我正在创建的整个React库，以及一个demo/工作区，该工作区仅导入react模块并显示它以用于测试。

我认为问题在于这两者如何相互作用以及输出块的位置或其他内容，但无法弄清楚。

我的文件是这样的：

lib / webpack.config.js

var path = require('path')

module.exports = {
  entry: {
    maps: './src/index.js'
  },
  output: {
    path: __dirname + '/dist',
    filename: 'index.js',
    library: 'Map',
    libraryTarget: 'umd'
  },
  module: {
    rules: [
      {
        test: /\.[s]?css$/,
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              importLoaders: 1,
              modules: {
                  localIdentName: "[name]__[local]___[hash:base64:5]",
                }
            }
          },
          'sass-loader'
        ],
        include: /\.module\.[s]?css$/
      },
      {
        test: /\.[s]?css$/,
        use: ['style-loader', 'css-loader', 'sass-loader'],
        exclude: /\.module\.[s]?css$/
      },
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            rootMode: 'upward'
          }
        }
      },
      {
        test: /\.svg$/,
        use: ['@svgr/webpack']
      },
      {
        test: /\.(jpe?g|png)$/i,
        loader: 'file-loader?name=/public/icons/[name].[ext]'
      }
    ]
  },
  resolve: {
    modules: [
      path.resolve(__dirname, 'src'),
      path.resolve(__dirname, '../node_modules')
    ],
    extensions: ['.js', '.jsx']
  },
  externals: {
    // Use external version of React
    react: 'react',
    'react-dom': 'react-dom'
  },
  // NOTE: @claus added options to fix files not being watched
  watchOptions: {
    aggregateTimeout: 300,
    poll: 1000
  }
}
