我不知道为什么我得到这个错误，我在任何地方都找不到答案。我已经卸载了react-router-dom包并重新安装了它，但它仍然告诉我交换模块没有从react-router-dom导出。这是我的代码。
我得到的错误是:
试图导入错误:“Switch”没有从“react-router-dom”中导出。
Code
import React from 'react';
import './App.css';
import NavBar from './components/navbar.js';
import Footer from './components/footer.js';
import Home from './components/pages/homepage/home.js';
import { BrowserRouter as Router, Switch, Route, Link } from 'react-router-dom';
function App() {
return (
<Router>
<div className="app-container">
<NavBar />
<Switch>
<Route path="/home" component={Home} />
</Switch>
<Footer />
</div>
</Router>
);
}
export default App;
改变
import { BrowserRouter as Router, Switch, Route, Link } from "react-router-dom";
<Switch>
<Route path="/home" component={Home} />
</Switch>
to
import { BrowserRouter as Router, Routes, Route, Link } from "react-router-dom";
<Routes>
<Route path="/home" element={ <Home />} />
</Routes>
如果你正在使用react-router-dom v6，你必须改变Switch到Routes，如下面的例子所示:
而不是导入Switch，
import {Switch，…} from 'react-router-dom';
进口航线
import{路由，…} from 'react-router-dom';
然后，不要使用component ={ComponentName}，而是使用element={<ComponentName/>}，如下所示:
import { Routes, Route, ...} from 'react-router-dom';
.
.
.
<Routes>
<Route exact path='/' element={<Home/>}></Route>
</Routes>
语法已经改变
旧的语法
import { BrowserRouter as Router, Switch, Route, Link } from "react-router-dom";
<Switch>
<Route path="/home" component={Home} />
</Switch>
新语法:
import { BrowserRouter as Router, Routes, Route, Link } from "react-router-dom";
<Routes>
<Route path="/home" element={<Home/>} />
</Routes>
