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

如果你正在使用一个更新版本的react-router-dom(例如，在我的例子中是^6.2.1)，你应该将<Switch>更改为<Routes>，并使用<Route>和component={<SampleComponent />}参数。

特别是下面的代码示例:

import { BrowserRouter as Router, Routes, Route} from 'react-router-dom';
import MyComponent from './containers/MyComponent';

export default function AppRoutes() {
    return (
        <Routes>
            <Route exact path="/" component={<MyComponent />}>
            </Route>
        </Routes>
    );
}

其他回答

写入<路由>而不是<交换机>。

在终端中运行:

npm install --save react-router react-router-dom

这对我很有帮助。或检查文件包。在“react-dom”后面添加以下内容:“^17.0.2”，

 "react-router": "^6.0.0",

我解决了我的错误，通过改变我渲染我的路线使用元素的方式。

To:

import React from "react";
import { BrowserRouter as Router, Route, Routes } from "react-router-dom";
import { Home } from "./app";
import { Login, Register } from "./auth";
const R: React.FC = () => {
  return (
    <Router>
      <Routes>
        <Route path="/login" caseSensitive={false} element={<Login />} />
        <Route path="/register" caseSensitive={false} element={<Register />} />
        <Route path="/" caseSensitive={false} element={<Home />} />
      </Routes>
    </Router>
  );
};
export default R;

基本上在v6之前。*:

import React from "react";
import { BrowserRouter as Router, Route, Switch} from "react-router-dom";
import { Home } from "./app";
import { Login, Register } from "./auth";
const R: React.FC = () => {
  return (
    <Router>
      <Switch>
        <Route path="/login">
           <Login />
        </Route>
       <Route path="/register">
           <Register/>
        </Route>

       <Route path="/">
           <Home/>
        </Route>
      </Switch>
    </Router>
  );
};
export default R;

在v6 . *

import React from "react";
import { BrowserRouter as Router, Route, Routes } from "react-router-dom";
import { Home } from "./app";
import { Login, Register } from "./auth";
const R: React.FC = () => {
  return (
    <Router>
      <Routes>
        <Route path="/login" caseSensitive={false} element={<Login />} />
        <Route path="/register" caseSensitive={false} element={<Register />} />
        <Route path="/" caseSensitive={false} element={<Home />} />
      </Routes>
    </Router>
  );
};
export default R;

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>
  );
}

如果你正在使用react-router-dom v6，看起来Switch已经被Routes取代了。

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
