System: OSX 10.9.5, Rails 4.0.12
After cloning a repo for a demo app (Ruby 2.1.5, Rails 4.1.0), I used rvm to install and then switch to an older version of Ruby, so I could run the demo app. I had some issues running the demo app, so I went back to my main project app (Ruby 2.2.4, Rails 4.0.12), tried to run rails s and got:
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
Well that's just silly. Rails was just here a moment ago. I tried switching gemsets within Ruby 2.2.4, even closing terminal in between, but still Rails was "not installed". These are my gemsets:
gemsets for ruby-2.0.0-p481 (found in /Users/localflavor/.rvm/gems/ruby-2.0.0-p481)
=> (default)
global
gemsets for ruby-2.1.5 (found in /Users/localflavor/.rvm/gems/ruby-2.1.5)
=> (default)
global
gemsets for ruby-2.2.1 (found in /Users/localflavor/.rvm/gems/ruby-2.2.1)
=> (default)
global
gemsets for ruby-2.2.2 (found in /Users/localflavor/.rvm/gems/ruby-2.2.2)
=> (default)
global
gemsets for ruby-2.2.4 (found in /Users/localflavor/.rvm/gems/ruby-2.2.4)
=> (default)
global
gemsets for ruby-2.3.0 (found in /Users/localflavor/.rvm/gems/ruby-2.3.0)
=> (default)
global
The gems included in ruby2.2.4@default:
$ gem list

Rails, where are you? I've tried rvm get master, reinstalling ruby 2.2.4, openssl, and bundler. I've tried every solution that seemed relevant from this SO question. All of this to no avail.
Interestingly enough, I am also unable to install the latest version of Ruby (2.4.0).
$ rvm install ruby 2.4.0
ruby-2.4.0 - #removing src/ruby-2.4.0..
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.9/x86_64/ruby-2.4.0.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

There has been an error while running make. Halting the installation.
I'm assuming Rails is here, just not being seen. Just like bundler and openssl. Something is up and I don't know where else to look. How can I find it and get it back in action?
UPDATE
Though my SSL issues are still unresolved, I was able to do this workaround to get Rails up and running again (thanks Kevin-T!)
Since Rails was missing from both gemsets for ruby 2.2.4 (thanks 7stud for the gem list pointers), I needed to reinstall it. But I was getting this error when I ran gem install rails -v 4.0.12
ERROR: While executing gem ... (Gem::Exception)
Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources
So I chose option 2: use a non-HTTPS source. In order to do that, I ran gem source to confirm that my source was https:
*** CURRENT SOURCES ***
https://rubygems.org/
I added the new http version with gem source --add http://rubygems.org :
https://rubygems.org is recommended for security over http://rubygems.org
Do you want to add this insecure source? [yn] y <-- I said yes
http://rubygems.org added to sources
I checked that it was added with gem source:
*** CURRENT SOURCES ***
https://rubygems.org/
http://rubygems.org <-- the new one
Then removed the https one with gem source --remove https://rubygems.org/:
https://rubygems.org/ removed from sources
At this point, running gem install rails -v 4.0.12 worked. Check out this post to install without the bulky documentation.
