如果你还没安装node环境及搭建项目请看这篇文章 这是一个行内链接：搭建项目及基础配置。

elementPlus的使用

• 安装依赖

npm install element-plus --save

• 下载elment-plus按需导入插件

npm i unplugin-vue-components unplugin-auto-import

• vite.config.ts中配置

import { fileURLToPath, URL } from 'node:url'
import postCssPxToRem from 'postcss-pxtorem'
import { defineConfig, loadEnv, UserConfig, ConfigEnv } from 'vite'
import vue from '@vitejs/plugin-vue'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'

// https://vitejs.dev/config/
export default defineConfig(({ mode  }: ConfigEnv): UserConfig => {
  const env = loadEnv(mode, process.cwd())
  return {
    plugins: [
      vue(),
      AutoImport({
        imports: ['vue', '@vueuse/core'],
        eslintrc: {
          enabled: false,
          filepath: './.eslintrc-auto-import.json',
          globalsPropValue: true
        },
        resolvers: [
          ElementPlusResolver() // 自动导入 Element Plus 相关函数，如：ElMessage, ElMessageBox... (带样式)
        ],
        vueTemplate: true,
        dts: false // 配置文件生成位置(false:关闭自动生成)
        // dts: "src/types/auto-imports.d.ts",
      }),
      Components({
        resolvers: [
          ElementPlusResolver() // 自动导入 Element Plus 组件
        ],
        dirs: ['src/**/components'], // 指定自定义组件位置(默认:src/components)
        dts: false // 配置文件位置(false:关闭自动生成)
        // dts: "src/types/components.d.ts",
      })
    ],
    //解决“vite use `--host` to expose”
    base: './',	//不加打包后白屏
    resolve: {
      alias: {
        '@': fileURLToPath(new URL('./src', import.meta.url))
      }
    },
    // 提前进行依赖包的预加载
