所以我发现问题出在您的Header组件中. 您正在使用与react-router-dom不兼容的引导程序.有关更多信息，请在google上查找.

So I found the issue lies in your Header component. You are using bootstrap which is not compatible with react-router-dom. For more information, kindly look it up on google.

这是您应该更改的内容:

Here is what you should change:

import { Link } from "react-router-dom";

<Nav.Link as={Link} to="/jargons">
   Jargons that works!
</Nav.Link>
