我正在尝试安装Gherkin 2.1.5,好吧,实际上它是
https://github.com/opencongress/opencongress的依赖.我在代码的根目录中使用bundle install来安装,大约有20-30个软件包已经安装好了,现在我被困在这个.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.

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并认为我很好.谢谢你的建议.
解决方法
gem install gherkin -v’2.1.5′ – –with-cflags = -w
为我做了诀窍.
