Vue路由设置正确但页面无内容显示，如何解决？

Question

在对vue进行路由配置的时候遇到了页面是空白的问题，用两个最简单的页面配置完也是同样的问题，渲染不出来东西，下面是我的相关代码，也没有任何的报错
index.js

import { createRouter, createWebHistory } from "vue-router";

// 引入
import About from "../components/AboutView.vue";
import Home from "../components/HomeView.vue";

// 路由信息
let routes = [
  {
    path: "/",
    name: 'home',
    component: Home,
  },
  {
    path: "/about",
    name: 'about',
    component: About,
  },
];

// 路由器
const router = createRouter({
  history: createWebHistory(), // HTML5模式
  routes,
});

export default router;

main.js

import { createApp } from 'vue';
import App from './App.vue';

// 引入插件
import router from './router';
// 安装router插件
createApp(App).use(router).mount('#app')

App.vue

<template>
  
  <div>
    <router-link to="/">Home</router-link> |
    <router-link to="/about">About</router-link><br />
    <router-view></router-view> 
  </div>
</template>

<script>

export default {
  name: 'App',
  data(){
    return {
    message:"学习Vue"
    }
  }
  
}
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

想要成功渲染
