Can any one please help me to resolve this problem.My ruby version is ruby 2.0.0. 'm trying it more than 2 days.Is this error is because of my mac os x10.9?? I have seen some sites saying that it will work only for mac os x10.6 and 10.7.

thanks in advance

Can you try this where "Simulator" is the same as what you have in the config.yml

ZUCCHINI_DEVICE="Simulator" zucchini run features/
