I'm not really a ruby person, but this seems to be a json lib conflict.

I guess it is nothing that cupertino does wrong, its just how life is with gems.

I made a Gemfile:

source ''
# gem 'json', '1.7.7'
gem 'cupertino'

use bundle to isolate the environment:

bundle install

bundle exec ios login

and life goes on.

thanks !
