尝试导入错误:“Switch”没有从“react-router-dom”导出

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;

当前回答

你必须先检查npm包的版本。执行npm info react-router-dom version命令查看。

如果包版本为>= 6.0.0，则必须进行更改

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

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

也必须改变

<Route path="/home" component={Home} />

<Route path="/home" element={<Home/>} />

其他回答

我和杂志海报上的人面临着同样的问题。我尝试了以下所有的方法:

卸载并安装react-router-dom 分别从react-router-dom导入Switch

但对我来说什么都没用。

请遵循以下指示。我相信你不会再得到错误。

正确的代码:

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, Routes, Route, Link } from "react-router-dom";

function App() {
  return (
    <Router>
      <div className="app-container">
        <NavBar />
        <Routes>
          <Route path="/home" element={<Home/>} />
        </Routes>
        <Footer />
      </div>
    </Router>
  );
}

export default App;

注意:Switch已经被替换为Routes，我们需要使用element而不是component。

这是一个使用react-router-dom V6的例子

import React from 'react'
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom'

import '../styles/global.css'

import Layout from '../containers/Layout'
import Home from '../pages/Home'
import Login from '../containers/Login'
import RecoveryPassword from '../containers/RecoveryPassword'
import NotFound from '../pages/NotFound'

const App = () => {
  return (
    <Router>
      <Layout>
        <Routes>
          <Route exact path="/" element={<Home/>}/>
          <Route exact path="/login" element={<Login/>}/>
          <Route exact path="/recovery-password" element={<RecoveryPassword/>}/>
          <Route path="*" element={<NotFound/>}/>
        </Routes>
      </Layout>
    </Router>
  );
}

export default App;

如果你正在使用react-router-dom的版本6，请使用这个

另外，请参考这里:https://reactrouter.com/docs/en/v6/upgrading/v5#:~:text=single%20route%20config%3A-，//%20This%20is%20a%20React%20Router%20v6%20app，%7D，-This%20step%20is

// This is a React Router v6 app
import {
  BrowserRouter,
  Routes,
  Route,
  Link,
  Outlet
} from "react-router-dom";

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="users" element={<Users />}>
          <Route path="me" element={<OwnUserProfile />} />
          <Route path=":id" element={<UserProfile />} />
        </Route>
      </Routes>
    </BrowserRouter>
  );
}

function Users() {
  return (
    <div>
      <nav>
        <Link to="me">My Profile</Link>
      </nav>

      <Outlet />
    </div>
  );
}

export 'Switch'(作为'Switch'导入)在'react-router-dom'中找不到

第一种方法[用路由替换交换机]

import { Routes , Route , Link } from 'react-router-dom';
<Routes>
 <Route exact path='/'>
  <HomePage />
 </Route>
</Routes>

第二种方法[将react-router-dom版本降级至版本5或以下]

npm i react-router-dom@5.0.0
