    各位老哥,今天第一次自己尝试搭建使用 React 就碰壁了,求帮忙。 我想用 react-router-dom 和 react-router-config 搭建路由的,但是失败了。

    // index.tsx
    import React from 'react'
    import ReactDOM from 'react-dom'
    import './index.css'
    import App from './App'
    
    ReactDOM.render(
      <React.StrictMode>
        <App/>
      </React.StrictMode>,
      document.getElementById('root')
    )
    
    // App.tsx
    import React from 'react'
    import {BrowserRouter as Router} from 'react-router-dom'
    import {renderRoutes} from 'react-router-config'
    import routes from './routes'
    
    function App() {
      return (
        <Router>
          {renderRoutes(routes)}
        </Router>
      )
    }
    
    export default App
    
    
    // routes/index.ts
    import Login from '../pages/Login'
    import Homepage from '../pages/Homepage'
    
    const routes = [
      {
        path: '/',
        component: Homepage
      },
      {
        path: '/login',
        component: Login
      }
    ]
    
    export default routes
    
    

    运行后,页面报错如下:

    Error: Invariant failed: You should not use <Switch> outside a <Router>
    

    但是我没有是使用 Switch 啊

    // packages.json 如下
    {
      "name": "my-react-app-ts",

    renderRoutes 是会创建 <Switch>的 , 所以有这个报错
    你把 <Router>{renderRoutes(routes)}</Router> 外层 Router 去掉试试

    非常感谢!后后台修改了源和尝试使用了 yarn 来进行安装,发现一切正常了。
