I'm trying to install Ruby on Rails v5 on OS X Yosemite 10.10.5, following the instructions on the rails site:
http://railsapps.github.io/installrubyonrails-mac.html
When I run this:
sudo gem install rails --version 5.0.0 --no-ri --no-rdoc
I get the error ERROR: Failed to build gem native extension.
Here are parts of the output on my command line that might be useful:
current directory: /Users/me/.rvm/rubies/ruby-2.3.0/lib/ruby/gems/2.3.0/gems/nokogiri-1.6.8/ext/nokogiri

RUBY VERSION: 2.3.0p0. RUBYGEMS VERSION: 2.5.1
xcode-select is successfully installed.
Thanks!
I solved it.
The error had to do with nokogiri. I installed it separately with the -- --use-system-libraries parameter:
gem install nokogiri -- --use-system-libraries
and I managed afterwards to install rails without errors.
