我目前正在使用 webpack 4 和 react loadable 来创建块。它实际上块取决于断点。但是，供应商规模保持不变。React loadable 还不支持 webpack 4 吗？或者我缺少一些设置？

css实际上似乎分成了块，虽然

{
  output: {
    path: 'tothe path',
    publicPath: `/publicPath/`,
    filename: '[name] + '.js',
    chunkFilename: '[name]',
  },
  resolve: {
    extensions: ['.js', '.json', '.css'],
    alias: aliases
  },

  stats: {
    warnings: false,
    children: false,
  },

  optimization: {

    splitChunks: {
      chunks: "all",
      name: true,
      cacheGroups: {
        common: {
          name: "vendor" + ".js",
          test: /[\\/]node_modules[\\/]/,
          chunks: "all",
          enforce: true,
          reuseExistingChunk: false,
        },
      }
    }
  }
}
