I am trying to install Ruby on Rails via RVM on Yosemite. Everything seems to have worked, though, when I attempt to run 'bundle install' I am presented with an error relating to Nokogiri:
pauls-air:~ paulmcguane$ gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

This could take a while...

Answer 1

I just did a full installation of Rails and Ruby and everything you need. I followed these steps.
https://gorails.com/setup/osx/10.10-yosemite
and use the following to install nokogiri
xcode-select --install
gem install nokogiri
bundle config build.nokogiri --use-system-libraries
bundle install

Answer 2

I got this to work using macports instead of homebrew. My configuration:
Install the latest Xcode Beta (Beta 3 at time of writing).
xcode-select --switch /Applications/Xcode-Beta3
macports built/installed from source, per installation instructions here
sudo port install libxml2 libxslt
gem install nokogiri -- --with-iconv-include=/opt/local/include/
A little convoluted, but everything worked fine after that.
