vue4.0引入elementui报错？

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
createApp(App).use(store).use(router).use(ElementUI).mount('#app')
按照elementui官网那么使用，在浏览器上报错？

不知道是什么原因造成的？

回答

哪有vue4,是vue3吧

vue4.0引入elementui报错？

一般的库要兼容vue3都要重写，因为api变化太大
