1. 按需加载antdesign
   不安装babel,分别安装组件和样式
   // import Button from “ant-design-vue/lib/button”;
   // import “ant-design-vue/lib/button/style”;

配置babel后
import { Button } from “ant-design-vue”;

加载全部组件
// import “ant-design-vue/dist/antd.less”;
import Antd from “ant-design-vue”;

2. 路由配置
   • 包含一个重定向
   • 顶层有个component的布局
   • 子组件采用import的动态引入

     {
       path: "/user",
       component: () => import("./layout/UserLayout"),
       children: [
         {
           path: "/user",
           redirect: "/user/login"
         },
         {
           path: "/user/login",
           name: "login",
           component: () =>
             import(/* webpackChunkName: "about" */ "./views/User/Login")
         },
         {
           path: "/user/register",
           name: "register",
           component: () =>
             import(/* webpackChunkName: "about" */ "./views/User/Register")
         }
       ]
     },
