怎么改写成vue3语法，老师？
Vue3.0.0
//main.js
import {createApp} from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import ElementUI from 'element-plus'
import 'element-plus/lib/theme-chalk/index.css'
import './static/css/base.less'
import './globalComponents'
const app = createApp(App)
app.use(store)
app.use(router)
app.use(ElementUI)
app.mount('#app')globalComponent/index.js
import { createApp } from 'vue'
import App from '../App.vue'
import AccountLogin from "../components/accountLogin/AccountLogin"
createApp(App).component('AccountLogin', AccountLogin)在App.vue中调用组件
<div> <accout-login></accout-login> </div>
无效，结果显示不了组件，不知道哪出问题，老师vue3该怎么改写
