在标题中,我在安装gem RedCloth时遇到问题.我下载了
RubyGems v1.8.24,并使用ubuntu 12.04,这是我的控制台日志：
kuba@kuba-P5Q-SE:~$sudo gem install RedCloth
[sudo] password for kuba:
Building native extensions. This could take a while...
ERROR: Error installing RedCloth:

Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.9 for inspection.

解决方法
尝试从Synaptic安装ruby1.9.1-dev软件包,或使用apt-get.
在命令提示符中：
sudo apt-get install ruby1.9.1-dev
mkmf(无法加载的模块)是only included in the development package for ruby on ubuntu.
