页面不渲染，报错了，哪里不对吗

二种方式都有错误 (index.vue 代码） <template> <div> helloword </div> </template> (index.js 代码） import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld' // import demo1 from '@/pages/demo1/index.vue' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld }, { path: '/demo1', name: 'demo1', component: require('@/pages/demo1/index.vue') } ] })
