Error to install Nokogiri on OSX 10.9 Maverick?

Question

I upgraded my OSX (Lion) to Mavericks and I can't install Nokogiri for my projects.

I already install XCode 5.0.1, Command Line Tools (using xcode-select --install), and already installed libxml2 from Homebrew and I am still having problems.

The error is:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.  /Users/ericcamalionte/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb checking for libxml/parser.h... *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling. 

I installed libxml2, libxslt and libiconv from Homebrew, and set the params to install Nokogiri, but don't work too.

I can't find what's wrong in my enviroment, can you help me?

Answer 1

You can also install Nokogiri on Mac OS X 10.9 Mavericks with full XCode Install using:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2 

Update

For those using Yosemite the following command will work:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --use-system-libraries 

or, it might actually be in your MacOSX10.11.sdk folder (mine was as of 18-Sep-2015) anyways, so even if you are not yet fully up to El Capitan, I had recently updated XCode and you may need to use the El Capitan SDK path, which follows next:

Update

For those using El Capitan the following command will work:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2 --use-system-libraries 

Update

For those using Sierra the following command will work:

gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2 --use-system-libraries 

Answer 2

After navigating the animated GIFs here, all that I had to do was simply xcode-select --install and the gem install nokogiri worked fine.
