Functions are not valid as a React child. This may happen if you return a Compon

react项目中配置路由是出现以下报错

Functions are not valid as a React child. This may happen if you return a Component instead of from render. Or maybe you meant to call this function rather than return it.

原因是老版本的react-router-dom,component的值，可以直接写，而新版的react-router-dom，elemen的值需要用</>包裹。

原代码

修改后
