在App.vue 里面写

<template>
 <div id="app">
  <div id="nav">
   <router-link to="/select">选择管理员</router-link>
  </div>
  <router-view/>
 </div>
</template>

在router 下面的index.js 里面添加路由

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'

Vue.use(VueRouter)

const routes = [
 {
  path: '/',
  name: 'Home',
  component: Home
 },
 {
  path: '/about',
  name: 'About',
  component: function () {
   return import('../views/About.vue')
  }
 },
 // 创建的路由
 {
  path: '/select',
  name: 'Select',
  component: () => import('../components/selest.vue')
 }
]

const router = new VueRouter({
 mode: 'history',
 base: process.env.BASE_URL,
 routes
})

export default router
