Angular2 Http with RXJS Observable TypeError: this.http.get(...).map(...).catch is not a function

It seems that the catch operator isn't imported.

You could try to import it like this:

import 'rxjs/add/operator/catch'

Or more generally this if you want to have more methods for observables:

import 'rxjs/Rx';
