Ionic package ios problem

hi everyone. i have a problem with ionic package build ios on windows. I followed ionic package tutorial (http://docs.ionic.io/docs/ios-build-profiles) and my console displays next error:

  id       │ 37
  status   │ FAILED
  platform │ ios
  mode     │ release
  started  │ Jul 25th, 2016 13:25:00

output:

=== BUILD TARGET KolTaxi OF PROJECT KolTaxi WITH CONFIGURATION Release ===

Check dependencies
Code Sign error: No code signing identities found: No valid signing identities (
i.e. certificate and private key pair) were found.

** BUILD FAILED **

But i have .p12, .cer, .mobileprovision sertificates. What’s wrong?

I’m with this problem. Suggestions?
