any idea what it could be or how i could fix that? i need cocoapods for an app, but its a nightmare :-)

I had the same error on a new Mac because I forgot to run "pod setup" after installing cocoapods. Because of that the specs repo was missing and the "pod install" command failed. Hope it helps you, too!
