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='/'>
    
            </Route>
          </Routes>
        </Router>
        </>
      );
    }
    
    export default App;

其他回答

一个解决方案:

删除“node_modules”文件夹。在包装里。Json文件，更改react-router-dom版本(在我的情况下版本6)为“react-router-dom”:“^5.2.1”

然后在终端运行:

NPM install用于安装依赖项，然后运行 NPM开始重新启动

在安装react-router-dom v6.0.2后，我得到了这个错误。

用路由替换交换机解决了这个问题:

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

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>

在react-router-dom v6中，“Switch”被替换为路由“routes”。您需要更新从的导入

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

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

您还需要更新Route声明

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

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

在react-router-dom中，你也不需要在Route声明中使用exact。

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;
