无法安装RedCloth

Question

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:
    ERROR: Failed to build gem native extension.

        /usr/bin/ruby1.9.1 extconf.rb
/usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load     such file -- mkmf (LoadError)
    from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from extconf.rb:1:in `<main>'


Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.9 for     inspection.
Results logged to /usr/lib/ruby/gems/1.9.1/gems/RedCloth-    4.2.9/ext/redcloth_scan/gem_make.out

我试着调查这个最后给定的文件,但是当我寻找它时,它会打开chrome,并给我错误.:(

尝试从Synaptic安装ruby1.9.1-dev软件包,或使用apt-get.

在命令提示符下:sudo apt-get install ruby​​1.9.1-dev

mkmf(无法加载的模块)仅包含在ubuntu上的ruby开发包中.
