Question

我在使用react-router-dom的主React组件中遇到了相同的TypeScritp错误。所有子组件都返回错误：

error TS2322: Type 'typeof NotFound' is not assignable to type 'StatelessComponent<void | RouteComponentProps<any>> | ComponentClass<void | RouteComponentProps<a...'.
  Type 'typeof NotFound' is not assignable to type 'ComponentClass<void | RouteComponentProps<any>>'.
    Types of parameters 'props' and 'props' are incompatible.
      Type 'void | RouteComponentProps<any> | undefined' is not assignable to type '{} | undefined'.
        Type 'void' is not assignable to type '{} | undefined'.


error TS2322: Type 'typeof Index' is not assignable to type 'StatelessComponent<void | RouteComponentProps<any>> | ComponentClass<void | RouteComponentProps<a...'.
  Type 'typeof Index' is not assignable to type 'ComponentClass<void | RouteComponentProps<any>>'.
    Type 'Index' is not assignable to type 'Component<void | RouteComponentProps<any>, ComponentState>'.
      Types of property 'props' are incompatible.
        Type 'Readonly<{ children?: ReactNode; }> & Readonly<Props>' is not assignable to type '(Readonly<{ children?: ReactNode; }> & void) | (Readonly<{ children?: ReactNode; }> & Readonly<Ro...'.
          Type 'Readonly<{ children?: ReactNode; }> & Readonly<Props>' is not assignable to type 'Readonly<{ children?: ReactNode; }> & Readonly<RouteComponentProps<any>>'.
            Type 'Readonly<{ children?: ReactNode; }> & Readonly<Props>' is not assignable to type 'Readonly<RouteComponentProps<any>>'.
              Property 'match' is missing in type 'Readonly<{ children?: ReactNode; }> & Readonly<Props>'.

我的Main.tsx组件看起来像这样（所有其他components.tsx似乎编译没有问题）：

import * as React from 'react';
import { BrowserRouter as Router, Route, Switch} from 'react-router-dom';

import Index from './Index';
import Explore from './Explore';
import NotFound from './NotFound';

class Main extends React.Component<{},{}> {

  render () {

    return (
      <Router>
          <Switch>
            <Route path="/" exact={true} component={Index} />
            <Route path="/explore/things/:id" component={Explore} />
            <Route component={NotFound} />
          </Switch>
      </Router>
    )

  }
}

export default Main;

任何人都可以提供一些线索吗？

Answer 1

这修复了编译错误（但是创建了一个tslint违规）

<Route path="/" exact={true} component={Index as any} /> <Route path="/explore/things/:id" component={Explore as any} />

Answer 2

我这样做

import { RouteComponentProps } from 'react-router-dom';

class Index extends React.Component<RouteComponentProps<any>, {}> {...}

或

import { RouteComponentProps } from 'react-router-dom';

interface Props extends RouteComponentProps<any> {...}
class Index extends React.Component<Props, {}> {...}

Answer 3

这可以通过箭头函数调用Route组件并使用spread传递props: any来解决：

<Route 
  path="/explore/things/:id"
  component={(props: any)=>
    <Explore {...props} user_role={this.state.user_role} />
  } />

此方法很不错，因为它允许您将其他道具user_role传递给React路由器子组件。

或者，更改@types/react-router-dom定义似乎摆脱了错误：

interface RouteProps {
    ...
    //component?: React.SFC<RouteComponentProps<any> | void> | React.ComponentClass<RouteComponentProps<any> | void>;
    component?: any;

但这似乎不是一个很好的解决方案。
