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;
在react-router-dom v6中，开关被路由替换。下面是配置react-router-dom v6的简单示例。
import * as React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Layout from './components/Layout';
import ProtectedRoute from './components/ProtectedRoute';
import LoginPage from './pages/LoginPage';
import WizardPage from './pages/WizardPage';
import RequestsPage from './pages/RequestsPage';
import './App.scss'
export class App extends React.Component {
public render() {
const sharedRouteProps = { exact: true, authenticationPath: '/login' };
const wizardRouteProps = { ...sharedRouteProps, path: "/", component: WizardPage };
const requestsRouteProps = { ...sharedRouteProps, path: "/requests", component: RequestsPage };
return (
<Layout>
<Router>
<Switch>
<Route exact path='/login' component={LoginPage} />
<ProtectedRoute {...wizardRouteProps} />
<ProtectedRoute {...requestsRouteProps} />
</Switch>
</Router>
</Layout>
);
}
}
