错误：useHref() 只能在 a 的上下文中使用<router>成分</router>

Question

**When i Write my My Nav Bar Component Content Directly in My Router Component. It works Fine But When I write that content in a NavBar Component it Generates the following error

Error: useHref() may be used only in the context of a component. .**

Im Using "react-dom": "^17.0.2", "react-router-dom": "^6.0.0-beta.6",

Following are my Components..

My NavBar Component:-

import { Link } from "react-router-dom";
// import styles from './NavBar.module.css';
export const NavBar = () => {
  return (
      <nav>
        <Link to="/"> Home </Link>
        <Link to="/about"> About </Link>
        <Link to="/product"> Product </Link>
      </nav>
  );
}

My Route Component:-

import { BrowserRouter as Router, Switch, Route, Routes} from "react-router-dom";

// importing Component's
import { Home } from "./Components/Home/Home";
import { About } from "./Components/About/About";
import { Products } from "./Components/Products/Products";
import { ProductItems } from "./Components/ProductItems/ProductItems";
import  {NavBar}  from "./Components/NavBar/NavBar";
import { Fotter } from "./Components/Fotter/Fotter";

export const RouterConfig = () => {
  return (
    <Router>
      <NavBar />
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route exact path="/product" component={Products} />
        <Route path="/product/:id" component={ProductItems} />
        <Route path="*" component={() => <h2>404 Not Found </h2>} />
      </Switch>
      {/* <Fotter />' */}
    </Router>
  );
};

import {BrowserRouter as Router} from "react-router-dom";

Use in components App.js or above in index.js and wrap your component in Router. Then the problem will disappear;-) In Your case I see two option:

1. index.js

 import React from "react"; import ReactDOM from "react-dom"; import App from "./App"; import { BrowserRouter as Router } from "react-router-dom"; ReactDOM.render( <React.StrictMode> <Router> <App /> </Router> </React.StrictMode>, document.getElementById("root") );

OR use App Component instead of RouterConfig Component.

2. App.js

 import { BrowserRouter as Router, Switch, Route, Routes} from "react-router-dom"; // importing Component's import { Home } from "./Components/Home/Home"; import { About } from "./Components/About/About"; import { Products } from "./Components/Products/Products"; import { ProductItems } from "./Components/ProductItems/ProductItems"; import {NavBar} from "./Components/NavBar/NavBar"; import { Fotter } from "./Components/Fotter/Fotter"; export const App = () => { return ( <Router> <NavBar /> <Switch> <Route exact path="/" component={Home} /> <Route path="/about" component={About} /> <Route exact path="/product" component={Products} /> <Route path="/product/:id" component={ProductItems} /> <Route path="*" component={() => <h2>404 Not Found </h2>} /> </Switch> {/* <Fotter />' */} </Router> ); };

I tried to explain it as best I could. Hope this helps you;-) Best Greetings and Good Luck, If you're still confused, check out here => React Router V6 - Error: useRoutes() may be used only in the context of a <Router> component

export is not running properly and causing an error. Can you retype it like below and try?:

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

const NavBar = () => {
  return (
      <div>
        <Link to="/"> Home </Link>
        <Link to="/about"> About </Link>
        <Link to="/product"> Product </Link>
      </div>
  );
}
export default Navbar;

Also, you don't need curly brace for import statement. import NavBar from "./Components/NavBar/NavBar";

If problem still persists, you can check your file paths because you are repeating folder names twice, it looks suspicious to me. Maybe you mean this: import NavBar from "./Components/NavBar";
