reactjs – React-router typescript类型错误

在使用打字稿创建我的反应应用程序时,我遇到了一个我尚未能解决的小问题.

我的代码：

App.tsx

import  * as React from 'react';
import * as ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import { BrowserRouter, Route, Switch } from 'react-router-dom';
import * as promise from 'redux-promise';
import reducers from './reducers';
import TemplateNavTop from './components/layout/template-nav-top';
const TestComponent2 = () => {
  return <h1>TestComponent</h1>;
}

const createStoreWithMiddleware = applyMiddleware(promise)(createStore);

ReactDOM.render(
<Provider store={createStoreWithMiddleware(reducers)}>
    <BrowserRouter>
        <Switch>
            <Route path="/" exact component={TestComponent} />
            <Route path="/checkout">
                <TemplateNavTop>
                    <TestComponent2 />
                </TemplateNavTop>
            </Route>
        </Switch>
    </BrowserRouter>
</Provider>
, document.getElementById('root')

模板导航顶

import * as React from 'react';
import NavTop from './nav-top/nav-top';
export default class TemplateNavTop extends React.Component<any, {}> {
  render() {
    return (
        <div>
            asd
            {this.props.children}
            Footer
        </div>
    );
  }
}

问题出现在/ checkout路线中,它抱怨以下内容：

Type '{ path: "/checkout"; children: Element; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Route> & Readonly<{ children?: ReactNode; }> & Rea...'.
  Type '{ path: "/checkout"; children: Element; }' is not assignable to type 'Readonly<RouteProps>'.
    Types of property 'children' are incompatible.
      Type 'Element' is not assignable to type '(props: RouteComponentProps<any>) => ReactNode'.

我发现以下解决方法确实有效：

<Route path="/checkout" component={() => TemplateWithNavBar(<TestComponent2 />)} />

但我宁愿以正确的方式去做,这里的任何人都可以帮助我吗？

编辑：我安装了@types

编辑和TL; DR：只需升级您的类型声明

npm install --save-dev @types/react-router

说明

这是声明文件中的错误.问题是最初预计会有孩子的类型

((props: RouteComponentProps<any>) => React.ReactNode | React.ReactNode)

它实际上是一个返回React.ReactNode |的联合函数React.ReactNode,它折叠成一个简单的React.ReactNode.

它究竟应该是什么

((props: RouteComponentProps<any>) => React.ReactNode) | React.ReactNode

我已经开了a pull request for you here.

我应该提一下,你可能不想依赖这种行为.我在网上找到的几乎所有例子都在使用react-router传递函数时为子节点使用了显式属性. Even the documentation itself says that it only takes a function(而不是元素或其他任何东西).
