main.js和router/index.js代码如下，其中很多式样都取消了，留下最简单的路由还是有问题。不知道是不是版本的原因。

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

console.log("环境变量",import.meta.env)

const app = createApp(App)

app.use(router).mount('#app')

import { createRouter, createWebHashHistory } from "vue-router";
import Home from '../components/Home.vue'

const routes = [
    {
        name: 'home',
        path: '/',
        meta:{
            title:'首页'
        },
        component: Home
    }
]

const router = createRouter({
    history:createWebHashHistory,
    routes
})

export default router
