具有React 16.6的React Router Suspense“提供给Route的对象类型为无效的道具prop组件，预期为功能". [英] React Router with React 16.6 Suspense "Invalid prop `component` of type `object` supplied to `Route`, expected `function`."

问题描述

我正在将React的最新版本(16.6)与react-router(4.3.1)配合使用，并尝试使用React.Suspense进行代码拆分.

I'm using the latest version (16.6) of React with react-router (4.3.1) and trying to use code splitting using React.Suspense.

尽管我的路由工作正常，并且代码确实分成了多个动态装入的包，但我收到有关不返回函数，而是将对象返回给Route的警告.我的代码:

Although my routing is working and the code did split into several bundles loaded dynamically, I'm getting a warning about not returning a function, but an object to Route. My code:

import React, { lazy, Suspense } from 'react';
import { Switch, Route, withRouter } from 'react-router-dom';

import Loading from 'common/Loading';

const Prime = lazy(() => import('modules/Prime'));
const Demo = lazy(() => import('modules/Demo'));

const App = () => (
  <Suspense fallback={<Loading>Loading...</Loading>}>
    <Switch>
      <Route path="/" component={Prime} exact />
      <Route path="/demo" component={Demo} />
    </Switch>
  </Suspense>
);

export default withRouter(App);

控制台警告如下: Warning: Failed prop type: Invalid prop `component` of type `object` supplied to `Route`, expected `function`.

正常导入将返回一个函数，但是使用lazy()的动态导入将返回一个对象.

A normal import would return a function, but the dynamic import with lazy() is returning an object.

对此有任何解决办法吗?

Any fixes for this?

推荐答案

尝试使用render道具代替component

<Route path="/" render={()=> <Prime />} exact />
<Route path="/demo" render={()=> <Demo />} />
