Install Nokogiri 1.6.1 under Ruby 2.0.0p353 (rvm based installation) fails (OSX Mavericks)?

Question

I\'ve tried to install Nokogiri 1.6.1 under Ruby and RVM but is failing with the following error:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build         


        

Answer 1

Turned out there is a bit simpler solution:

Remove this line in your ~/.bashrc or ~/.bash_profile file:

GREP_OPTIONS="--color=always"

with this one:

export GREP_OPTIONS="--color=auto"

This way you won't need to install any duplicates. Thanks to MrPowers @ Nokogiri Issues.
