json-1.7.7 vs json-1.8.1 Gem::LoadError

[crucialfelix]

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

cupertino-0.9.5

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

I made a Gemfile:

source 'https://rubygems.org'
# gem 'json', '1.7.7'
gem 'cupertino'

use bundle to isolate the environment:

bundle install

bundle exec ios login

and life goes on.

thanks !
