react-router-dom TypeScript TS2322: Type 'typeof Index' is not assignable to type

Question

Im getting quite a few of the same TypeScritp error in my main React component using react-router-dom. All of the child components are returning errors:

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>'.

My Main.tsx component looks like this (all other components.tsx seem to compile without issue):

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;

Can anyone provide some clues?

Answer 1

This fixes the compile error (but creates a tslint violation)

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