react中create-react-app配置antd按需加载（方法二）

1.yarn add babel-plugin-import

2.在根目录下的package.json下的bable中添加相应代码

"babel": {
    "presets": [
      "react-app"
    ],
    "plugins": [
      [
        "import",
        {
          "libraryName": "antd",
          "style": "css"
           // 引入样式为 css
           // style为true 则默认引入less
        }
      ]
    ]
  }

3.重启项目yarn run start
