Observable error ? (Return type of public method from exported class has or is using name 'Observable' from external module )

[dmastag]

Hi There,
Ionic2 just released version RC0 which is using Angular2, and when I tried it with the SDK I got the errors below. Since they are showing in the sdk folder I wondered if this problem is with the SDK or with Ionic2. Any pointers would be appreciated. (Still learning ngModule so not understanding it might also be the problem)

Hi @dmastag thanks for reaching me out, it seems that the rxjs module "Observable" is not found or somthing like that, not sure why it says "cannot be named" I haven't seen that error before, I will try to replicate this issue.

Ok, let me know if you need any info from me.

Importing Observable in your service files (/services/custom) fixes the problem:
import { Observable } from 'rxjs/Observable';

Additionally you have to import it in base.service.ts. The file error.service.ts requires importing ErrorObservable as following.
import { ErrorObservable } from 'rxjs/observable/ErrorObservable';
