vue-router实现简单vue多页切换、嵌套路由、路由跳转的步骤和报错

npm i vue-router@3.6.5          //npm
//or
yarn add vue-router@3.6.5       //yarn

<template>
  <h1>Home</h1>

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

//1、创建路由组件

const routes = [
  { path: '/home', component: Home },
  { path: '/user', component: User },
]

const router = new VueRouter({
  routes, // (缩写) 相当于 routes: routes

export default router

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'
import User from '../views/User.vue'
import Main from '../views/Main.vue'
Vue.use(VueRouter)
//1、创建路由组件
//2、将路由与组件进行映射
const routes = [
  //主路由
  {
    path: '/',
    component: Main,
    children: [
      //子路由
      { path: '/home', component: Home },
      { path: '/user', component: User },
    ],
  },
  { path: '/home', component: Home },

// 3. 创建 router 实例，然后传 `routes` 配置
// 你还可以传别的配置参数, 不过先这么简单着吧。
const router = new VueRouter({
  routes, // (缩写) 相当于 routes: routes
})
export default router
