AntDesign按需引入

1.安装babel-plugin-import

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

2.暴露webpack.config.js

npm run eject

3.1在根目录(src)下新建.babelrc文件：

.babelrc文件配置如下

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

3.2在package.json中直接配置
