1.配置package.json

主要看的是 "build:all": "vue-cli-service build && vue-cli-service build --mode test && vue-cli-service build --mode development",

  "scripts": {"dev": "vue-cli-service serve","build:prod": "vue-cli-service build","build:test": "vue-cli-service build --mode test","build:all": "vue-cli-service build && vue-cli-service build --mode test && vue-cli-service build --mode development","build": "pkg src/server/admin_web_server.js -t node12-win-x64,node12-linux-x64 -o my-server","build:stage": "vue-cli-service build --mode staging","preview": "node build/index.js --preview","lint": "eslint --ext .js,.vue src","test:unit": "jest --clearCache && vue-cli-service test:unit","test:ci": "npm run lint && npm run test:unit","svgo": "svgo -f src/icons/svg --config=src/icons/svgo.yml"},

2.新增你需要的环境

.env.development 

# just a flag
ENV = 'development'

 .env.production

# just a flag
ENV = 'production'

 .env.test

# just a flag
ENV = 'test'

3.修改vue.config.js中的 outputDir

module.exports = {
...publicPath: '/',outputDir: 'dist-'+process.env.ENV,assetsDir: 'static',lintOnSave: false,productionSourceMap: false,
...
}

 outputDir 是打包后输出的目录;也可按照其他方式命名，每个环境不一样即可

 4.打包

终端执行：npm run  build:all

搞定
