If you are using node version higher than 6.x.x. Try following code. It will fix the issue.

import {Observable} from 'rxjs';

where should I add this path? – Sufian Uddin Jun 07 '18 at 09:41
Search where you have used rxjs-compat/Observable and replace that with this. – Prachi Jun 07 '18 at 09:44

If you are using angular version 6 then You can use

// creation and utility methods

import { Observable, Subject, pipe } from 'rxjs';

// operators all come from rxjs/operators

import { map, takeUntil, tap } from 'rxjs/operators';
