webpack 采坑（CleanWebpackPlugin 插件报错： CleanWebpackPlugin is not a constructor ；）
坑一： CleanWebpackPlugin 插件报错： CleanWebpackPlugin is not a constructor ；
webpack.config.js配置如下：
const CleanWebpackPlugin = require("clean-webpack-plugin");
...
plugins: [ new CleanWebpackPlugin(['dist']) ]；
正确写法：
const { CleanWebpackPlugin } = require("clean-webpack-plugin");
...
plugins: [ new CleanWebpackPlugin() ]
