react引入antd按需加载警告“You are using a whole package of antd, please use...“

1. react引入antd后报出黄色警告You are using a whole package of antd, please use https://www.npmjs.com/package/babel-plugin-import

2. 此时需要引入babel-plugin-import按需加载

npm install babel-plugin-import --save-dev

3. 在根目录下新建文件babelrc
   

{
  "plugins": [
    ["import", { "libraryName": "antd", "style": "css" }]
  ]
}

4. 重启项目，警告消失
