一、安装

https://element-plus.gitee.io/zh-CN/guide/installation.html

方法一：使用vue ui命令

方式二：打开命令行，进入项目目录中，执行命令

npm install element-plus --save
npm install @element-plus/icons-vue

第一步：打开命令行输入vue ui 进入可视化的界面管理工具

C:\Users\Lenovo>vue ui

�  Ready on http://localhost:8000

第二步：点击依赖安装，搜索 element-plus，选中安装

第三步：项目中配置element-plus和icons-vue（开发项目直接copy就可以）

import { createApp } from 'vue'

//导入安装的element-plus
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import * as ElementPlusIconsVue from '@element-plus/icons-vue'
import App from './App.vue'
import zhCn from 'element-plus/dist/locale/zh-cn.mjs'

const app = createApp(App)

//注册element-plus
app.use(ElementPlus,{
	locale: zhCn,
})

//注册图标库
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
  app.component(key, component)
}

app.mount('#app')
