导入 element-ui 快速开发
1、安装 element-ui：

npm i element-ui

2、在 main.js 中引入 element-ui 就可以全局使用了。

import ElementUI from ‘element-ui’

import ‘element-ui/lib/theme-chalk/index.css’

Vue.use(ElementUI)

3、将 App.vue 改为 element-ui 中的后台布局

4、添加测试路由、组件，测试跳转逻辑

(1) 、参照文档 el-menu 添加 router 属性

(2) 、参照文档 el-menu-item 指定 index 需要跳转的地址

Babel
Babel 是一个 JavaScript 编译器，我们可以使用 es 的最新语法编程，而不用担心浏览器兼

容问题。他会自动转化为浏览器兼容的代码

Webpack
自动化项目构建工具。gulp 也是同类产品
