Angular2 rxjs falta observable.método del intervalo

Estoy tratando de usar el método de intervalo de un observable, pero sigo recibiendo el error

 Property 'interval' does not exist on type 'Observable<any>'.

He añadido estas importaciones:

import "rxjs/Rx";
import "rxjs/add/observable/interval";
import "rxjs/observable/IntervalObservable";

Si desea crear un interval (Observable) con rxjs v6.2.1:

import { interval } from 'rxjs';
// instead of:
// import { Observable } from 'rxjs/Observable';
// import 'rxjs/add/observable/interval';

const counter = interval(1000); 

// instead of:
// const counter = Observable.interval(1000);

import {Observable} from 'rxjs/Observable';
import 'rxjs/Rx'

  printX:number;
  ngOnInit() {
    const myInterval = Observable.interval(1000);
    myInterval.subscribe((x : number)=>{
      this.printX=x;
    });

Necesita importar la clase Observable de esta manera para poder usar el método interval:

import {Observable} from 'rxjs/Rx';

O

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/observable/interval';
