自动清理dist目录下的旧文件
为了在每次打包发布时自动清理掉dist目录中的旧文件，可以安装并配置clean-webpack-plugin插件：
// 1.安装清理dist目录的webpack插件
npm install --save-dev clean-webpack-plugin
// 2.按需导入插件、得到插件的构造函数之后，创建插件的实例对象
const {CleanWebpackPlugin} = require('clean-webpack-plugin')
// 3.把插件挂载到plugins节点中
plugins: [htmlPlugin, new CleanWebpackPlugin()]
