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;

          <Routes>
            <Route path='/'>

          </Routes>
        </Router>
        </>
      );
    }
    
    export default App;

我也有同样的问题。在项目终端上，输入以下命令。您不需要对代码进行任何更改。

      );
    }
    
    export default App;

在react-router-dom v6中，Switch被替换为Routes。使用以下格式:

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

<Router>
    <Routes>
        <Route exact path="/" component={component} />
        <Route exact path="/path2" component={component2} />
        <Route exact path="/path3" component={component3} />
    </Routes>
</Router>

如果你正在使用react-router-dom的版本6，那么你需要用路由更新Switch。下面的语法适合我:

import { BrowserRouter as Router, Route, Routes } from "react-router-dom";
import './App.css';
import Home from './components/Home';

function App() {
  return (
    <div>
      <Router>
        <Routes>
          <Route path="/" exact element={<Home />} />
        </Routes>
      </Router>
    </div>
  );
}

export default App;

react-router-dom包最近发生了突破性的变化。React Router v6 Changelog永久链接

所以你所需要的就是重命名导入，就像这样…

import { Routes as Switch, Route } from 'react-router-dom';

干杯!
