新版本的React-Route (v6或以上，但不排序后续版本还会有修改)，移除了Switch，写法和老版本有一些区别，下面分享一个示例：

 JSX文件:

import React, {StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import { BrowserRouter as Router, Route, Routes ,Link } from "react-router-dom";
import Home from './components/Home';    //根据路由显示的子组件，自己定义
import About from './components/About';  //根据路由显示的子组件，自己定义//路由 begin
export function Navigation() {
return (<nav><ul><li><Link to="/">首页</Link></li><li><Link to="/about">关于</Link></li></ul></nav>)
}export default function App() {return (<Router><Navigation /><Routes><Route path="/" element={<Home />} /><Route path="/about" element={<About />} /></Routes></Router>)
}
//路由 end//错误边界
class ErrorBoundary extends React.Component {constructor(props){super(props)this.state = { hasError: false }}static getDerivedStateFromError(error){return {hasError:true}}componentDidCatch(error, info){console.log(error, info)}render(){ if(this.state.hasError){  return <h1>Something went wrong.</h1>} return this.props.children}
}createRoot(document.getElementById('root')).render(<StrictMode><ErrorBoundary><App /></ErrorBoundary></StrictMode>)

入口html页面引用上面的jsx文件，比如

<script type="module" src="/src/main.jsx"></script>
