Where is ruby stored on mac?

Question

I am looking for a path of where ruby gets stored on mac?

I installed macruby on my mac and I am trying to see where it got installed. I want to include the path of macruby in my ruby script. When I do rvm list, I get:

=> macruby-0.12 [ i686 ]
 * ruby-1.9.3-p545 [ x86_64 ]
   ruby-2.1.1 [ x86_64 ]
   ruby-2.1.2 [ x86_64 ]
   ruby-2.1.2-version [ x86_64 ]

I use #!/usr/local/bin/macruby in my ruby script, but looks like macruby is not present in that location. When I execute "whereis ruby" command on I get back "/usr/bin/ruby", but when I execute "whereis ruby-1.9.3-p545" or "whereis macruby-0.12" I get nothing.

How do I find the path of where does all these ruby versions lie?

There is a neat command you can do in your Terminal. `gem env`. It will show you `RUBY EXECUTABLE` along with a lot of more useful locations. — Justin, Aug 14 '14 at 16:29

You can get the path to the local executable with

$ which ruby

the rvm rubies are in your rvm directory, which I believe is ~/.rvm/rubies (I use rbenv so not sure about the details)

The which command should pickup whatever shims/other magic RVM is using to set your shell ruby

Hmmm I use homebrew. Looks like it's same for rbenv and homebrew too. I found it under the same path. Thanks John!! – tech_human Aug 14 '14 at 16:33

that will only tell somebody if they already have ruby installed – barlop Mar 21 '19 at 11:53
`which ruby` and `type -P ruby` >> `/Users/me/.rubies/ruby-2.6.2/bin/ruby` give the location of the currently activated Ruby, at least on my High Sierra macOS using chruby. `whereis ruby` >> `/usr/bin/ruby` gives the location of the system Ruby. My testing conditions were `chruby ruby-2.6.2`. – Greg Jun 13 '19 at 15:53
