I am new to Angularjs2, I am not able to build the application Angular2MVC referred in the article. I tried multiple solutions suggested over google, but still not able to resolve, I am receiving few errors as below:

1 Error Build:Class 'WebSocketSubject<t>' incorrectly extends base class 'AnonymousSubject<t>'. Angular2MVC F:\MyLabs\Angular2MVC\node_modules\rxjs\observable\dom\WebSocketSubject.d.ts 23

2.

export declare class Subject<T> extends Observable<T> implements ISubscription {

3.

What I have tried:

I tried installing new version of TypeScript, I tried to install different versions of TypeScript like 2.4.0 etc, different version of rxjs in Package.json as suggested over google. Also I discarded package.json which is part of the article and tried to create new one with npm init from the command prompt, but the issue is still not resolved.
