crack

我猜它与我的ruby版本有关?

你的Gem Path指的是Ruby 2.1.0

- GEM PATHS:
 - /Users/joshuahornby/.rvm/gems/ruby-2.1.0

而针对Ruby 2.0.0-p353安装了crack gem

/Users/joshuahornby/.rvm/gems/ruby-2.0.0-p353/gems/crack-0.4.2

这就是问题.我模拟了与你相同的安装,我的GEM_PATH与破解宝石路径相匹配.

这是我推荐的.首先卸载gem crack.在你的应用程序路径中运行rvm使用2.1.0,然后执行bundle install.
