this is from the ionic push docs:
ionic plugin add https://github.com/phonegap-build/PushPlugin.git
ionic add ngCordova
ionic add ionic-service-core
ionic add ionic-service-push
angular-websocket is required by Ionic Push, and should have been automatically installed in the previous step
however, after I follow with the steps, I still can not see any files related to angular-websocket.
how can I solve this? or can I skip these files?
plz advise. thx!
