Anyone know how to resolve this?
I have tried to change to rxjs@5.0.0-beta.6 in package.jason, and install the warning dependies but alwase the same problem.

I will suggest you to use an earlier version of the library angular2-jwt, e.g. 0.1.13, as the latest versions of Angular 2 (after 2.0.0-beta.15) contain many breaking changes and are not supported by Ionic 2 yet.

i.e.

npm install angular2-jwt@0.1.13

Worked for me, thanks! :slight_smile:
