I was trying to install the new ruby 2.0.0 on my system but keep on getting error (I wish I saved the error message but I didn’t, sorry!).
Next I went and tried updating Xcode and still can’t install the new ruby 2.0.0. I ended up installing rvm like this;
And it worked! Woohoo!
But then referring to Daniel Kahoe of RailApps;
This guide shows how to install the most recent stable release (Rails 3.2.12), plus a version of Rails patched for Ruby 2.0 (Rails 3.2.13.rc2), and the newest version of Rails (Rails 4.0.0.beta1).
It seems like ruby 2.0.0 should (at least) be used in combination with Rails 3.2.13.rc2. Make sure to check that
rvm gemset list and
rvm list after installing ruby 2.0.0.
EDIT: Luckily I posted the error message on NatashaTheRobot’s blog which means anyone with the same issue can check my post above.
