我有一个没有任何 rails、merb 等框架的 ruby​​-javascript 项目。Gem 已成功安装，但是当我尝试初始化 jasmine 时，jasmine init我收到了以下消息：

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]

宝石文件：

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

如何解决这个问题？谢谢

PS1。似乎bundle exec jasmine init应该工作，但我有另一个错误：

你需要让你的 rails 安装依赖于根 Gemfile 中的 rack 1.3.0，或者尝试让 jasmine 依赖于 rack 1.2.1
