我有一些问题创建一个路由器使用路由器在vuejs上。我的文件main.js就像下面的代码，然后当我改变添加一些路由，我得到了下面的错误
MAIN.JS之前（运行良好）

import 'bootstrap/dist/css/bootstrap.css'
import { createApp } from 'vue'
import Vue from 'vue'
import App from './App.vue'
import router from './router'
    
import VueRouter from 'vue-router'
import store from './store'
    
createApp(App).use(store).use(router).mount('#app')

主JS之后

import 'bootstrap/dist/css/bootstrap.css'
import Vue from 'vue'
import App from './App.vue'

import VueRouter from 'vue-router'
import store from './store'

import testeRouter from './pages/testeRouter'

Vue.use(VueRouter)

const router = new VueRouter({
    routers: [
        {
            path: '/pages/testeRouter',
            component: testeRouter
        }
    ]
})

Vue.createApp(App).use(store).use(router).mount('#app')

错误信息

TypeError: Cannot read properties of undefined (reading 'use')

页面不再呈现了。我已经花了一段时间试图修复它。有人知道它可能是什么吗？谢谢
