1.使用ant-design-vue或者element-ui时，如何每个组件都去import导入组件，大大降低了开发效率，如果全局一次性注册会增加项目体积，那么如何实现既不局部引入，也不全局注册？
2.在element-plus官网看到有说明
3.那么在webpack中也是可以使用的，下载unplugin-auto-import，unplugin-vue-components两款插件
pnpm install -D unplugin-auto-import unplugin-vue-components4.在vue.config.js中配置
const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { AntDesignVueResolver } = require('unplugin-vue-components/resolvers');AutoImport({imports: ['vue', 'vue-router'],resolvers: [AntDesignVueResolver()],}),Components({resolvers: [AntDesignVueResolver()],}),5.在项目中使用
<template><div id="app"><!-- <router-view></router-view> --><a-button>按钮</a-button><a-divider /></div>
</template><script>
export default {name: 'App',
}
</script><style>
#app {font-family: Avenir, Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;text-align: center;color: #2c3e50;margin-top: 60px;
}
</style>
6.发现报错：AutoImport is not a function，打印AutoImport发现是个对象，AutoImport.defalut才是函数，更改下vue.config.js配置
AutoImport.defalut({imports: ['vue', 'vue-router'],resolvers: [AntDesignVueResolver()],}),Components.defalut({resolvers: [AntDesignVueResolver()],}),7.运行项目还是报错
Module build failed (from ./node_modules/.pnpm/unplugin@2.2.0/node_modules/unplugin/dist/webpack/loaders/transform.js): Error [ERR_REQUIRE_ESM]: require() of ES Module
发现插件用的是es语法，而我们用的是commonjs语法，如何解决？降低插件版本
"unplugin-auto-import": "0.16.0","unplugin-vue-components": "0.22.0",8.运行之后发现没报错了，完美解决
