vue-cli4新增一个router，点击后router-view没有内容

Question

小小的实验下vue-cli4，新增一个demo1.vue,新加router，结果居然点击了没反应。错哪了？？


index.js

import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";

Vue.use(VueRouter);

const routes = [
  {
    path: "/",
    name: "home",
    component: Home
  },
  {
    path: "/about",
    name: "about",
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () =>
      import(/* webpackChunkName: "about" */ "../views/About.vue")
  },
  {
    path: "/demo1",
    name: "demo1",
    component: () => {
      import("../views/Demo1.vue");
    }
  }
];

const router = new VueRouter({
  mode: "history",
  base: process.env.BASE_URL,
  routes
});

export default router;

Demo1.vue

<template>
  <div class="demo1">
    <h1>This is an Demo1 page</h1>
  </div>
</template>
<script></script>

<style lang=""></style>

App.vue

<template>
  <div id="app">
    <div id="nav">
      <router-link to="/">Home</router-link>|
      <router-link to="/about">About</router-link>|
      <router-link to="/demo1">demo1</router-link>
    </div>
    <router-view />
  </div>
</template>

<style lang="scss">
#app {
  font-family: "Avenir", Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}

#nav {
  padding: 30px;

  a {
    font-weight: bold;
    color: #2c3e50;

    &.router-link-exact-active {
      color: #42b983;
    }
  }
}
</style>

path写错了

{
    path: "/demo1",
    name: "demo1",
    component: () => {
      import("../views/Demo1.vue");
    }
}

修改为

{
    path: "/demo1",
    name: "demo1",
    component: () => import("../views/Demo1.vue");
 }
