安装Gherkin 2.1.5的故障排除

Question

我正在尝试安装Gherkin 2.1.5,实际上它是https://github.com/opencongress/opencongress的依赖项.我bundle install在代码的根目录中使用安装,大约20-30个软件包已经安装,现在我坚持这个.我在跑步:

Linux 3.2.0-27-generic #43-Ubuntu SMP
Linux Mint 13 Maya

一旦停止安装,这是输出.

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/gherkin-2.1.5 for inspection.

我从来没有在ruby中编程,所以我对整个安装过程中的东西都有点脱节.我刚刚想出如何安装redcloth并认为我处于良好状态.谢谢你的建议.
