Unclear message when running a project and CocoaPod is not installed

When I tried to run a project which contained a CocoaPod it failed with a message from which it was not clear that I didn’t have CocoaPod installed. Maybe the message should guide you that you have to install them.

nchakaromac:locationtest nchakaro$ tns doctor
WARNING: CocoaPod is not installed or is not configured properly.
You will not be able to build your projects for iOS if they contain plugin with CocoaPod file.
To be able to build such projects, verify that you have installed CocoaPod.
These warnings are just used to help the NativeScript maintainers with debugging if you file an issue.
Please ignore them if everything you use NativeScript for is working fine.

sudo gem install cocoapods is clean enough.

@dtopuzov but I still got the warning WARNING: CocoaPods is not installed or is not configured properly.
