If you’re really interested in all the possible options, including ones I don’t recommend (such as installing Ruby with Homebrew), read my definitive guide to installing gems on a Mac.
INSTALLING RUBY ON RAILS MAC INSTALL
Glad you asked! The most reliable method, and the only one I recommend, is to install a separate and newer version of Ruby using a version manager. So what’s the proper way to install Rails on a Mac?

Here's the errors I'm getting: ERROR: Error installing redcarpet:ĮRROR: Failed to build gem native extension.
The problem is that a few days ago I upgraded to Mavericks OS and I'm not able to install it, but I'm not really sure if it has anything to do with the change of OS. I'm currently trying to install Redcarpet gem for a rails project.
