vue3使用element-plus

1、下载包

 npm install element-plus --save

2、引入

        全局引入+挂载：引入记得有css文件（下载不下来可能是项目正在运行，先关掉）

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')

        按需引入：先下载两个插件

 npm install -D unplugin-vue-components unplugin-auto-import --save

修改vue.config.js文件

const { defineConfig } = require('@vue/cli-service')
const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')
mod
