import Button from 'antd/lib/button'
import 'antd/lib/button/style'

npm run eject

 npm install babel-plugin-import -S

"babel": {
    "presets": [
      "react-app"
    ],
    "plugins": [
      [
        "import",
        {
          "libraryName": "antd",
          "libraryDirectory": "es",
          "style":"css"
        }
      ]
    ]
  }

  //安装插件:
   npm install babel-plugin-import -S
  //修改(添加)config-overrides.js文件
  //引入react-app-rewired添加babel插件的函数
  const {injetBabelPlugin}=require('react-app-rewired')
  module.exports=function override(config,env){
 config=injetBabelPlugin([
    [
        "import",
        {
          "libraryName": "antd",
          "libraryDirectory": "es",
          "style":"css"
        }
      ]
