vite2.x实现按需加载ant-design-vue@next组件的方法

yarn add vite-plugin-style-import -D or npm i vite-plugin-style-import -D

import vue from '@vitejs/plugin-vue'
import styleImport from 'vite-plugin-style-import';
/
  @type {import('vite').UserConfig}
 /
export default {
 plugins: [
  vue(),
  styleImport({
   libs: [{
    libraryName: 'ant-design-vue',
    esModule: true,
    resolveStyle: (name) => {
     return `ant-design-vue/es/${name}/style/css`;
    },
   }]
  })
 ]
}

import { createApp } from 'vue'
import App from './App.vue'
import { Input } from 'ant-design-vue';
const app=createApp(App)
app.use(Input)
app.mount('#app')

<template>
 <!-- script-setup内引入使用，不需注册-->
 <Button type="primary"> Primary</Button>
 <!-- 在mian.js使用use注册组件 -->
 <a-input placeholder="Basic usage" />
</template>
<script setup>
import { Button } from "ant-design-vue";
</script>
