Error installing Ruby on Rails 4.0 - atomic_refere

I am getting an error when trying to install rails (or more specifically, atomic).

Building native extensions.  This could take a while... ERROR:  Error installing rails:     ERROR: Failed to build gem native extension.

I'm basically just following the rails tutorial (for rails 4.0 and ruby 2.0, seen here) and have kind of hit a wall here, unfortunately, unable to find much info on what's happening here.

I found this question and followed both suggestions in the answer with the same result.

回答1:

Had the very same problem, coming from that same tutorial. Got it to work following this post. Ran a few command to compare gemsets with the post but what seem to fix the problem was

gem update --system (without the "2.0.0" from tutorial, updated me to 2.0.3)
gem update
gem install rails (again without specifying the version)

And finally it installed properly

回答2:

So, in my case what seems to be failing is that the Makefile has a INSTALL=./install and there is no ./install. I edited the Makefile to take out the ./ and then created a local spec with

gem spec ../../../cache/atomic-1.1.14.gem --ruby > ../../../specifications/atomic-1.1.14.gemspec

subsequent

gem install rails

succeeded, but no idea if this screwed up my rails instance.
