vue-cli4中使用Vue.use(VueRouter)报错问题

router/index.js中

vue-cli2中还是使用的import Vue  from 'vue'，Vue.use也没有问题

import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld } ] })

vue-cli4中不能直接import Vue from 'vue'

import { createRouter, createWebHashHistory } from 'vue-router' import Home from '../views/Home.vue' const routes = [ { path: '/', name: 'Home', component: Home }, { path: '/about', name: 'About', component: () => import(/* webpackChunkName: "about" */ '../views/About.vue') } ] const router = createRouter({ history: createWebHashHistory(), routes }) export default router
