我下载了老师的代码包，运行npm install 后 运行npm start, 报错了。

错误如下：

Error: Cannot find module 'html-webpack-plugin'

这个是添加html组件后的报错：

提示没有安装 html-webpack-plugin 这个模块，再重新 npm intall html-webpack-plugin 试试

  老师能不能理一下从下载代码之后到npm start 之后需要的配置命令呢？因为我加入html-webpack-plugin 之后启动npm 还是报错了

• 双越 回复 提问者 慕仰7173844 #2

  再把拨错截图发出来，肯定不和之前的报错一样了

  已经编辑原问题了，谢谢老师
