无法将react挂钩与react-router-dom一起使用

npm install react-router-dom@latest

yarn add react-router-dom@latest

import React, { useState, useEffect } from 'react';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';

function App() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    document.title = `You clicked ${count} times`;
  }, [count]);

  return (
    <Router>
      <div>
        <h1>Counter</h1>
        <p>You clicked {count} times</p>
        <button onClick={() => setCount(count + 1)}>Click me</button>

        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/about">About</Link>
          </li>
        </ul>

        <Route path="/" exact component={Home} />
        <Route path="/about" component={About} />
      </div>
    </Router>
  );
}

function Home() {
  return <h2>Home</h2>;
}

function About() {
  return <h2>About</h2>;
}

export default App;
