vue3.0 项目引用element-plus，运行项目报错，main.js代码如下

import Vue from 'vue'
import { createApp } from 'vue'
import App from './App.vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'

Vue.use(ElementPlus)
createApp(App).mount('#app')

vue3.0 main.js正确写法

import { createApp } from 'vue'
import App from './App.vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'

const app = createApp(App)

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