Property 'zip' does not exist on type 'typeof Observable'.

[alvipeo]

Just upgraded project to beta.3 and got zip does not exist on type 'typeof Observable'.
Other 2:

1. Property 'fromPromise' does not exist on type 'typeof Observable'.
2. Property 'take' does not exist on type 'ReplaySubject'.

What does it mean? (this is angular2 project).

Would you able to share code snippets how did you import rx into your codebases?

I've tried to reproduce this with master but so far no luck. @alvipeo , I'm closing this issue for now, please feel freely reopen anytime, if this is still occurs beta.4 or repo's master directly. It'd be appreciate if you can share snippet to reproduce issue.

I'm getting the exact same issue. I imported Observable in Angular 2 project from "rxjs/Observable". No solution on SO either.

[matthiaskomarek]

@ahmad2smile solved this issue by importing the zip operator like this

import 'rxjs/add/observable/zip';

I'm getting the same issue after upgrading to RxJS6
code:

import {BehaviorSubject, Observable} from 'rxjs';
//...
// trying to use zip method that returns Observable 
myMethod(params) {
    const places$: Observable<Place>[] = placesKeys
      .map(placeKey => this.placeService.fetchPlaceByKey(placeKey));

    return Observable.zip(...places$)     // <===== DOESNT WORK
      .map((places: Place[]) => {...})
      .flatMap((places: Place[]) => {...})
      // ...
  }

When I simply import zip from operators that chaining doesn't work Observable.zip(...places$).map

Please help me
