I am Getting below Error in Auth.d.ts file in Node_Modules Package.
[ts] Module \'node_modules/rxjs/Observable\"\' has no exported member \'Observable\'. import Observab
if your angular version is 6 and above.
use below:
import { take, map } from "rxjs/operators";
import { timer } from "rxjs/observable/timer";
Install - npm install --save rxjs-compat
Also user pipe with other funtions(Take,Map).
timer(0, 10) .pipe(take(1000)) .pipe(map(() => x));
