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?
gem env output:

Note: This question relates to How can I get bundler to use the Ruby version set by chruby and .ruby-version?.
Using chruby I have Ruby 1.8.7 installed on macOS:
$ ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin17.4.0]
Also, I have used gem update --system 1.8.30 to install a specific version of RubyGems which I am hoping is compatible. This would appear to be installed properly:
$ gem --version
1.8.30
However, my RubyGems environment shows the incorrect version of Ruby (2.5.0):
$ gem env
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.30
- RUBY VERSION: 2.5.0 (2017-12-25 patchlevel 0) [x86_64-darwin17]
- INSTALLATION DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7
- RUBY EXECUTABLE: /usr/local/opt/ruby/bin/ruby
- EXECUTABLE DIRECTORY: /Users/keithpitty/.gem/ruby/1.8.7/bin

How can I fix the RubyGems environment to use the version of Ruby that chruby has set?
My missing step was installing RubyGems 1.6.2 from source. Following advice elsewhere from Dan Cheail, I did the following:
curl -O https://rubygems.org/rubygems/rubygems-1.6.2.tgz
(and then unzipped it)
cd rubygems-1.6.2
chruby ruby-1.8.7-p374
ruby setup.rb
gem update --system 1.8.25
And then my RubyGems environment was fixed:
$ gem env
RubyGems Environment:

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'm having the following error after installing ruby on Windows 8, I've already uninstalled it several times, fired commands like gem cleanup, removed .gem folder, ruby folder, environment variables, btut nothing seems to work.
Here are the logs of the errors I am encountering

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?
RubyGems is reporting a different ruby version than running ruby --version. Looking for suggestions on diagnosing and fixing this. OS is OS X 10.5.

The problem is that you have a ruby executable in /opt/local/bin that was probably installed by macports at some point. Either deleting this ruby executable or removing /opt/local/bin from your PATH variable should solve your problem. gems is telling you exactly where it expects to find ruby and its associated executables:
RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
- EXECUTABLE DIRECTORY: /usr/bin
