    <p>I am very new to OS X and I don't know anything about compiling, MacPorts, Homebrew, etc. All I want to do is install the Nokogiri gem on OS X.</p> <p>In Windows, it was as simple as:</p> <pre><code>gem install nokogiri </code></pre> <p>However, when I try this on OS X, I get the following message:</p> <pre><code>Building native extensions. This could take a while... ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.4 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/nokogiri-1.4.4/ext/nokogiri/gem_make.out </code></pre> <p>Again, I am not very good with OS X and I have no idea what this means.</p> <p>Is there an easy way to install Nokogiri without having to mess with MacPorts and other programs I've read about online?</p> <p>I have XCode 4 installed (some people say XCode is required for this to work), and I'm using Ruby 1.8.7.</p> <p>Also, I tried installing MacPorts and following the instructions online and I get the following:</p> <pre><code>Derek-MacBook-Pro:~ derek$ sudo port install libxml2 libxslt Password: ---&gt; Computing dependencies for libxml2Error: Unable to execute port: can't read "build.cmd": Failed to locate 'make' in path: '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its MacPorts configuration time location, did you move it?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
