Question

I have a ruby-javascript project without any rails, merb and etc frameworks. Gem successfully installed but when I tried to initialize jasmine jasmine init I’ve got this message:

can't activate rack (~> 1.2.1, runtime) for ["actionpack-3.0.3", "railties-3.0.3"], 
already activated rack-1.3.0 for ["jasmine-1.0.2.1]

Gemfile:

source "http://rubygems.org"
gem "coderay"
gem 'ruby-debug19'
gem 'jasmine'

How to fix this problem? Thanks

P.S. Windows 7, DivKit

P.S.1. Seems that bundle exec jasmine init should work but I’ve got another error:

You need to make your rails installation depend on rack 1.3.0 in the root Gemfile, or try to make jasmine depend on rack 1.2.1
