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react-router-dom v6，看起来Switch已经被Routes取代了。

import React from "react";
import { Link, BrowserRouter as Router, Route, Routes } from "react-router-dom";
import "./App.css";
import App from "./App";
const RouterPage = () => {
    return (
        <Router>
            <div>
                <nav>
                    <Link to="/">Home</Link>
                    <Link to="/posts">Posts</Link>
                    <Link to="/">About</Link>
                    <Link to="/contact">Contact</Link>
                </nav>
                <Routes>
                    <Route exact path="/" element={<App />}></Route>
                    <Route path="/post" element={<App />} />
                    <Route path="/about" element={<App />} />
                    <Route path="/contact" element={<App />} />
                </Routes>
            </div>
        </Router>
    );
};

你应该把Switch换成Routes

在React路由器v6中，我们必须将组件替换为。通过执行npm install react-router-dom@latest命令，确保你的项目运行的是最新版本。如果你不想更新你的代码，你可以在你的项目根目录下运行npm install react-router-dom@5.2.0来安装react-router-dom的v5版本。

我可以通过将Switch更改为Routes来修复它。所以你应该有这样的东西:

<Routes>
  <Route path='/home' element={<Home/>} />
</Routes>

你还需要把import从Switch改成Routes:

import { Routes, Route } from "react-router-dom";

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;
