I have this error loading a ruby file:

I had a lot of problems tu install rubygems and now I have problems again with midiator gem. I think something is not well configured. It is like the paths are not properly configured (Midiator gem is installed), but I do not know how to fix this.
Turning this into an answer as it solved the problem:
Is it listed when you do gem list?

I wrote a homework assignment on my Mac at home and am now trying to run it on the Linux machines at school (where it will be graded) and am getting:
.rb:1:in `require': no such file to load -- socket (LoadError)
Obviously I am trying to use Ruby's socket class:
require 'socket'
Checking the schools ruby version I see: ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]
Shouldn't this version of the sockets? Am I doing something wrong? Anyway to get this to work?

I've successfully installed my ruby gem to a subdirectory of ~ using the --user-install option to gem. I can now see it under ~/.gem/ruby/1.8/gems/.
However, I'm unable to require it from my script:
./public_html/tt_web/index.cgi:2:in `require': no such file to load -- mbox (LoadError)
from ./public_html/tt_web/index.cgi:2
I added ~/.gem/ruby/1.8/bin to my PATH variable per the information here (and I've verified it actually worked with echo $PATH).
What else do I need to load gems from a custom path?
Here is the output of gem env, if it helps:

Well, I have no idea why this works, but adding require 'rubygems' to the top of my code fixed everything. Perhaps someone else could still shine some light on why, but I'm just happy it's working now :)
I recently installed Ruby 2.0.0 on OS X 10.8.3 by compiling from source code. I checked the version with
$ ruby --version
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.3.0]
And I checked my gem version with
$ gem env

I noticed that the reported version of Ruby here does not match the version I installed. I don't know if this matters or not.
I have a simple piece of code called encrypy.rb that I'm running. After installing the 'rsa' gem with gem install rsa.
require 'rubygems'
require 'rsa'
key = RSA::KeyPair.generate(128)
ciphertext = key.encrypt("message")
puts(ciphertext)
When I run it, it gives an error saying it can't find the gem.
$ ruby encrypt.rb -Idirectory '/Library/Ruby/Gems/1.8'
/usr/local/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- rsa (LoadError)
from /usr/local/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'
from encrypt.rb:2:in `<main>'
So the question is, why isn't Ruby finding the gem despite seeming to know where it is? And how can I fix it?
Ruby 1.8.7 is shipped with OS X. It seems that gem is seeing that version instead of your manually installed 2.0.0. As others already suggested, using RVM or rbenv (which one depends on personal preference) makes handling different ruby environments much easier. You can find those tools and descriptions for them in the following places:
RVM: https://rvm.io/
rbenv: https://github.com/sstephenson/rbenv
I was having some trouble running some Ruby scripts. While trying to get these scripts to run I tried lots of different things as well as updating rubygems as I thought this may be the problem. Since then I can't get any Ruby scripts to run.
I think that if I can revert rubygems back to it's original version I may be able to run Ruby scripts again, but I don't know how.

It seems that you have multiple versions of ruby(and gem) installed. It is advised to use rvm when maintaining multiple ruby versions. Or clean up your wrong/old/unneeded installations.
For downgrading Rubygems, you can do the following:
sudo gem update --system VERSION
You obviously have to put a real version there.
When I type:
gem env
on my Windows system, it produces this info:

When I go to the GEM path:
C:\Ruby\lib\ruby\gems\1.8\gems
I see many gem folders with all of the installed gems. But when I type
gem list local
I get an empty listing:
*** LOCAL GEMS ***
Why are the gems not findable?
I'm not sure, but i think the command is
gem list --local
gem list local tells RubyGems to list all gems whose name starts with the string local. (See gem help list for details.) Do you have any gems with that name installed? Otherwise, it's not really surprising that the list is empty.
