不能安裝RedCloth

Question

在標題中，我安裝寶石RedCloth時出現問題。我下載RubyGems的v1.8.24，並使用Ubuntu 12.04，這裏是我的控制檯日誌：

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 

我試圖尋找到這最後給定的文件，但是當我看着它，它會打開鍍鉻，並給了我錯誤。:(
