Did you run npm install after the upgrade? Looking at the error messages I would say that you’re trying to use the new syntax (i.e. *ngFor="let p of loggedInPages") in an older release of Angular 2 which needs the previous syntax (i.e. *ngFor="#p of loggedInPages"). Also make sure that you don’t have ionic serve running during the upgrade (or at least restart it after that) - see the linked post for details:
