1. Configure babelrc or add babel-loader in webpack
// .babelrc or babel-loader option
{
"plugins": [
["import", { libraryName: "antd", style: "css" }] // `style: true` 会加载 less 文件
]
}2. Component reference error: Do not add < /> to components defined using functions
ReactDom.render(WingBlankExample, document.body);
