麻烦你指教 ant-design-vue cdn 怎么配置

npm i --save--dev babel-plugin-import
npm WARN rollback Rolling back readable-stream@2.3.6 failed (this is probably harmless): EPERM: operation not permitted, rmdir 'F:\vsworspce\ant-desing-pro\node_modules\fsevents\node_modules'
npm WARN @ant-design/icons-vue@1.0.1 requires a peer of @ant-design/icons@~1.1.0 but none is installed. You must install peer dependencies yourself.

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.9: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}

老师，我都按照你的老写代码，报这个错误：
These dependencies were not found:

* ant-design-vue/es/button in ./src/main.js
* ant-design-vue/es/button/style in ./src/main.js

To install them, you can run: npm install --save ant-design-vue/es/button ant-design-vue/es/button/style
请老师帮忙看一下

老是帮我看看步骤和您的一样
import { Button } from 'ant-design-vue';
Vue.config.productionTip = false;
Vue.use(Button);

 presets: ["@vue/app"],
  "plugins": [
    ["import", {
      "libraryName": "antd",
      "libraryDirectory": "es",
      "style": true // `style: true` 会加载 less 文件
    }]
  ]


 css: {
    loaderOptions: {
      less: {
        // 这里的选项会传递给 css-loader
        javascriptEnabled: true
      }
    }
  }

    "babel-plugin-import": "^1.12.0", 也添加了
但app.js还是没有按需引入 还是12M

ant-design-vue 官方文档文档是这么说的（https://vue.ant.design/docs/vue/use-with-vue-cli-cn/#%E4%BD%BF%E7%94%A8-vue-cli-3-%E7%9A%84%E5%B0%8F%E4%BC%99%E4%BC%B4）

按下面的格式引入模块
```js
import { Button } from 'ant-design-vue';
Vue.component(Button.name, Button)
```

这么做了之后会报错：

```bash
 ERROR Failed to compile with 1 errors 19:31:35
This dependency was not found:
* core-js/modules/es6.function.name in ./src/main.js
To install it, you can run: npm install --save core-js/modules/es6.function.name
```

然后把 `Vue.component(Button.name, Button)` 这块改为老师讲的 `Vue.use(Button)` 就没问题了

这是怎么回事？
