vue3使用element-plus，全局加载配置

• Vue3报错：Failed to resolve component: xx If this is a native custom element, make sure to exclude it f
  原因是是使用icon时报错，应该是icon也要引入东西

• 安装

  npm install element-plus --save
  

• 代码

  //main.js文件
  import { createApp } from 'vue'
  // vue3使用element-plus的步骤一
  import ElementPlus from 'element-plus'
  import 'element-plus/dist/index.css'
  import * as ElementPlusIconsVue from '@element-plus/icons-vue'
  
  
  
  import App from './App.vue'
  
  
  // element-plus使用的步骤二，遍历完所有icon添加到app里
  const app = createApp(App)
  for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
      app.component(key, component)
    }
  
  app.use(ElementPlus)
  app.mount('#app')
  
  

  //x.vue 使用elementplus
  <el-icon :size="20">
      <Edit />
  </el-icon>
