清理文件管理插件clean-webpack-plugin

报错： TypeError: CleanWebpackPlugin is not a constructor

解决办法：

1. 把const CleanWebpackPlugin  = require('clean-webpack-plugin'); 改为

const { CleanWebpackPlugin } = require('clean-webpack-plugin');

2.  

 plugins: [  

        new CleanWebpackPlugin(['dist'])

    ]

改为

 plugins: [  

        new CleanWebpackPlugin()
