Strict Mode 会出错

[xiaoxiangmoe]

文件如下：

//   src/pages/index.js
export default ()=>'马猴烧酒'

//  src/layouts/index.js

import * as React from 'react';
export default (props)=>
<React.StrictMode>
    {props.children}
</React.StrictMode>

会出错

这是 react 的提示啊，跟 umi 没什么关系吧

这是 react-router 的问题，remix-run/react-router#6060
