解决creat-react-app安装v5报错找不到组件（初次）
config-overrides.js 文件

const { override, fixBabelImports, addPostcssPlugins } = require('customize-cra');

module.exports = override(
  fixBabelImports('import', {
    libraryName: 'antd',
    libraryDirectory: 'es', // 需要开放该配置
    style: 'css',
  }),
  addPostcssPlugins([
    require('postcss-pxtorem')({
      rootValue: 16,
      propList: ['*'],
    }),
  ]),
);
