withRouter HOC和getDerivedStateFromProps

Question

我尝试在一个组件中使用getDerivedStateFromProps，如下所示：

class MyComponent extends React.Component {
    constructor(props) {
        super(props);

        this.state = {
            location: '',
        };
    }

    static getDerivedStateFromProps(nextProps, prevState) {
        return {
            location: nextProps.location.pathname,
        };
    }

    render() {....}
}

const EnhancedComponent = withRouter(MyComponent);
export default EnhancedComponent;

并得到一个警告Stateless functional components do not support getDerivedStateFromProps.

withRouter返回的是无状态函数组件吗？我真的不明白这个警告的意思。会很想在这里得到一些阳光！

顺便说一句，派生状态正在被正确更新。

它确实与评论中提到的吊装有关。已在react-router 4.3.0-RC2 https://github.com/ReactTraining/react-router/issues/6057中修复
