报错信息：

Error: webpack.optimize.CommonsChunkPlugin has been removed, please use config.optimization.splitChunks instead.

问题原因：webpack 4版本废弃了 webpack.optimize.CommonsChunkPlugin, 但是中文网应用了该代码, 导致出错

解决办法：在webpack.config.js配置文件中 添加

optimization: { //  optimization 与 entry、plugins 同一级别    splitChunks: {      cacheGroups: {        commons: {          name: "commons",          chunks: "initial",          minChunks: 2        }      }    }  }
