main.js

import Vue from 'vue'
// 引用路由
import VueRouter from 'vue-router'
// 光引用不成，还得使用
Vue.use(VueRouter)
// 入口文件为 src/App.vue 文件 所以要引用
import App from './App.vue'
// 引用路由配置文件
import routes from './router/index.js'
// 使用配置文件规则
const router = new VueRouter({
routes
})
// 跑起来吧
new Vue({
router,
el: '#app',
render: (h) => h(App)
})

router/index.js

// 引用模板
import Hello from '../components/Hello.vue'
import Hi from '../components/Hi.vue'
import Hi1 from '../components/Hi1.vue'
import Hi2 from '../components/Hi2.vue'
// 配置路由
