ng2-opd-popup issue with angular4

Question

I installed ng2-opd-popup module and tried to import if from app.module.ts by importing "PopupModule.forRoot()". It produces following error.

I am using typescript version as 2.4.2 and rxjs version as 5.4.2. I tried to fix it using given solutions in rxjs/Subject.d.ts error : Class 'Subject<T>' incorrectly extends base class 'Observable<T>' and How do I get around this "Subject incorrectly extends Observable" error in TypeScript 2.4 and RxJS 5.x?. Both of solutions didn't work for me. Can anyone give any suggetions to fix this?

I applied ng2-opd-popup module here to have popup window by using button click event as my purpose.

in tsconfig.json file add following code snippet

  }
}
