reactjs - Hur man utökar react-router Router-klass med TypeScript?

Jag försöker utöka react-router Router-klass på detta sätt:

class RouterWrapper extends Router {
    componentWillMount() {
        super.componentWillMount();
    }
}

så jag har fått ett TypeScript-kompileringsfel TS2339: Property 'componentWillMount' does not exist on type 'Component<RouterProps, ComponentState>'. Alla nödvändiga typdefinitioner är installerade. Just nu har jag hittat en lösning:

class PatchRouter extends Router {
    componentWillMount?();
}

Sedan utvidgas från PatchRouter, men denna lösning är så ful.

Så, här är min fråga: Hur förlänger man Router korrekt med TypeScript 2.2?
