第一步：安装filemanager-webpack-pluginnpm install filemanager-webpack-plugin --save-dev第二步在vue.config.js中配置引入filemanager-webpack-pluginconst FileManagerPlugin = require('filemanager-webpack-plugin')修改configureWebpack项配置，增加打包操作配置方式一：configureWebpack: { plugins: [ new FileManagerPlugin({ events: { onEnd: { delete: ['./dist.zip'], archive: [{ source: './dist', destination: './dist.zip' }] } }
