vue3使用elenent-plus

问题：

当我按照官网的下载并且引入element-plus之后发现会报错，步骤如下：

步骤一下载：

npm install element-plus --save

步骤二在main.js中引入并注册

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

const app = createApp(App)

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

步骤三：在页面使用

    This is a message
    
  

当我感觉能够顺利进行下去的时候，结果就是报错

我一直苦苦寻找解决方案，怎么都不行，结果最后是删除依赖重新下载了。结果就可以了
