Element-plus按需加载

1、需安装unplugin-vue-components 和 unplugin-auto-import这两款插件

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

2、修改vite.config.js配置文件

import { defineConfig } from 'vite'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'

export default defineConfig({

　　plugins: [

    vue(),

    AutoImport({

      resolvers: [ElementPlusResolver()],

    }),

    Components({

      resolvers: [ElementPlusResolver()],

    }),

  ],

})
