Hi all,
After a couple hours looking up on google and having dependency issues I found out that ionic is using RxJS beta (5.0.0-beta.12) which is incompatible with Angular 2 jwt, angular2-jwt@0.1.28 requires a peer of rxjs@^5.0.0 but none was installed so if someone is having the same issue you need to use RxJS 0.1.27 npm install angular2-jwt@0.1.27
Cheers
