安装router依赖：npm install vue-router

index.js

import Vue from ‘vue‘
import VueRouter from ‘vue-router‘
import HelloWWorld from ‘../components/HelloWorld.vue‘
Vue.use(VueRouter)

export default new VueRouter({
	routes: [{
		path: ‘/‘,
		name: ‘HelloWWorld‘,
		component: HelloWWorld
	}]
})

main.js

import Vue from ‘vue‘
import App from ‘./App.vue‘
import router from ‘./router/index.js‘ //注意：这里引入的是router目录，百度上有好些是引入vue-router
Vue.config.productionTip = false

new Vue({
	router,
	render: h => h(App),
}).$mount(‘#app‘)
