类型上不存在属性“exact”

Question

我正在尝试在我的 React 应用程序中使用react-router-dom，并且我正在使用打字稿而不是 javascript。这里的问题是我无法将 Route 导入到我的组件中并使其工作。我已经安装了@types/react-router-dom，但由于某种原因它仍然无法按预期工作。

这是一个正在尝试使用的组件react-router-dom

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

const App = () => {
    return (
        <div>
            <Router>
                <div>
                    <Route path="/" exact/>
                </div>
            </Router>
        </div>
    )
}

export default App;

这就是我收到的错误

TypeScript error in /Users/veselinkontic/Projects/givellet/frontend/src/components/index.tsx(9,37):
Type '{ path: string; exact: true; }' is not assignable to type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.
  Property 'exact' does not exist on type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.  TS2322

     7 |             <Router>
     8 |                 <div>
  >  9 |                     <Route path="/" exact/>
       |                                     ^
    10 |                 </div>
    11 |             </Router>
    12 |         </div>

这是我的 package.json 文件，您可以在其中看到所有内容。

Answer 1

React Router v6 不再支持exact。

// 旧版 - v5 <Route exact path="/" component={Home} />

// 新 - v6 <Route path="/" element={<Home />} />

正如他们的文档中所述：

您不再需要使用精确的道具<Route path="/">。这是因为默认情况下所有路径都完全匹配。如果您因为有子路由而想要匹配更多 URL，请使用尾随 *，如 中所示<Route path="users/*">。

您可以参考此迁移指南：https ://reactrouter.com/en/main/upgrading/v5

Answer 2

对于 React Router v6，我将 Routes 和 Route 添加到导入中。

例子：

import { BrowserRouter, Route, Routes  } from 'react-router-dom';
import  Home  from "./pages/Home";
import  NewRoom  from "./pages/NewRoom";
    
function App() {
  return (
  <BrowserRouter>
      <Routes>
      <Route path="/"  element={<Home />}/>
      <Route path="/rooms/new" element={<NewRoom />}/>
      </Routes>
  </BrowserRouter>
  );
}
    
export default App;

Answer 3

我也遇到过同样的问题，新的 React-Router 不支持关键字exact。您只需将其从 <Route .../> 中删除即可，它就会正常工作。

另外，component您还必须使用element元素标签并将其传递给它。
