黄瓜无法在我的机器上运行

Question

黄瓜不知何故无法在我的机器上运行。现在在运行时

bundle show cucumber 

我得到了

/opt/local/lib/ruby/gems/1.8/gems/cucumber-1.0.6

，但是当我现在尝试在我的应用程序上运行这些功能时，我收到以下错误

bundle exec cucumber features

安装 RVM 的参考：

Answer 2

看起来捆绑程序找不到您的依赖项。您似乎正在使用系统范围的 ruby​​ 安装，这是不推荐的。

我建议您安装 rvm 并使用 rvm 的方法重新安装 ruby​​，然后在一切配置完毕并正常工作后再次运行bundle。
