解决vue-router 嵌套路由没反应的问题

//route.js
const App = () => import('../App.vue');
const Login = () => import('../component/Login.vue');
const Class = () => import('../component/Class.vue');
const CourseList = () => import('../component/CourseList.vue');
const CourseContent = () => import('../component/CourseContent.vue');
 
const routers = [{
  path:'/',
  component:App,
  children:[{
      path:'login',
      component:Login
    },{
      path:'class',
      component:Class
    },
    { 
      path:'course',
      children:[{
          path:'list',
          component:CourseList
        },{
          path:'content',
          component:CourseContent
        }
      ]
       
    },
  ]
}] 

export default routers

{
path:'course',
component:Course
children:[{
path:'list',
component:CourseList
},{
path:'content',
component:CourseContent
}
]
},

<template>
<div>
<router-view></router-view>
</div>
</template>

import Vue from 'vue'
import VueRouter from 'vue-router'

//引入两个组件
import recomView from '../components/views/ty/recom/view.vue'
import recomEdit from '../components/views/ty/recom/edit.vue'

Vue.use(VueRouter)

//建立router
const router = new VueRouter({
 mode: 'history',
 routes: [
 {
   path: '/recom',
   children: [
    {
     path: 'view',
     name: 'recomView',

    {
     path: 'edit',
     name: 'recomEdit',
     component: recomEdit
    }
   ]
  },
  
//暴露router，export default方式暴露出的模块在导入时可以起任何名（不冲突的情况下）
export default router

<template>
……
<router-view></router-view>
……
</template>

<script>
……
this.$router.push('/recom/view')
this.$router.push('/recom/edit')
……
</script>

//recom.vue，鉴于我这里并不需要这个'/recom'页面，所以以最简单的方式引入router-view就可以了
<template>
 <router-view></router-view>
</template>

import Vue from 'vue'
import VueRouter from 'vue-router'

//引入两个组件
import recomView from '../components/views/ty/recom/view.vue'
import recomEdit from '../components/views/ty/recom/edit.vue'

Vue.use(VueRouter)

//引入recom组件！
const recom = {
 template: `<router-view></router-view>`
}

//建立router
const router = new VueRouter({
 mode: 'history',
 routes: [
 {
   path: '/recom',
   component: recom,  //引入recom,必不可少
   children: [
    {
     path: 'view',

     component: recomView
    },
    {
