my ionic2 versions are

6.3.1

Ionic Framework Version: 2.0.0-rc.1
Ionic CLI Version: 2.1.0
Ionic App Lib Version: 2.1.0-beta.1
OS: Windows 7 SP1
Node Version: v4.5.0

Because of failing dependencies, I am getting compilation issues.

Have you included these dependencies in your app’s package.json?

thanks for the reply. Just need your clarification.

I upgraded Ionic2 from beta to RC two weeks back by uninstalling and installing ionic. I dont have these dependencies in my package.json and it got downloaded fine. But why now? Is there anything changed? Also when I ran “ionic info” from my new workspace, it shows Ionic Framework Version: 2.0.0-rc.1 where as the old workspace shows Ionic Framework Version: 2.0.0-rc.0. Does Ionic version automatically upgrades when we run npm install? Just curious.
