1.安装依赖：yarn add react-app-rewired customize-cra babel-plugin-import less less-loader
2.修改package.json
....
"scripts": {
"start": "react-app-rewired start",
"build": "react-app-rewired build",
"test": "react-app-rewired test",
"eject": "react-scripts eject"
},
....
3.根目录下创建config-overrides.js
//配置具体的修改规则
const { override, fixBabelImports,addLessLoader} = require('customize-cra');
module.exports = override(
fixBabelImports('import', {
libraryName: 'antd',
libraryDirectory: 'es',
style: true,
}),
addLessLoader({
lessOptions:{
javascriptEnabled: true,
modifyVars: { '@primary-color': 'green' },
}
}),
);
4.备注：不用在组件里亲自引入样式了，即：import 'antd/dist/antd.css'应该删掉
