I'm writing Ruby scripts on Linux Mint 14 under RVM. In both Ruby 2.0 and 1.9.3, when I try to run what I'm working on, I get the error:
/home/tom/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- Nokogiri (LoadError)

from make_index.rb:1:in `<main>'
Nokogiri is installed; gem list gives:

The file in question starts with require 'Nokogiri'. Running the file with sudo doesn't make a difference, nor does using the terminal vs. running it in Geany.
Not Nokogiri rather, you should write as below
require 'nokogiri'

/System/Library/Frameworks/Ruby.framework/Versions/2.0/... is the system library in OS X Yosemite.
Ruby 2.2 (or any other version) is installed by you or some other user -- perhaps via RVM, given you have some rvm gem installed? If so you need to use RVM to change the default. If you did not install RVM correctly or ignored some warning or command it gave to you, you might want to re-install.
If you did not install Ruby 2.2 via RVM*, here are instructions for changing OS X default Ruby installed using Brew.
(*I could not recommend RVM more strongly. Other people like rbenv to do the same job.)

Using jruby-1.6.7 via rvm and gem version 1.8.24 I created a new project containing a Gemfile:
source 'http://rubygems.org'
gem 'google-api-client'
and a main.rb:
require 'google/api_client'
After
gem install bundler
bundle install
gem list
I get

rubygems-update (1.8.24, 1.7.2)
rvm (1.11.3.3)
signet (0.3.4)
spoon (0.0.1)
But when I run ruby main.rb, it results in an error:
LoadError: no such file to load -- google/api_client
require at org/jruby/RubyKernel.java:1033
(root) at main.rb:1
On MRI everything seems to be working fine. The problem does not seem bound to any specific gem.
Can someone help me with this?
Unless you have JRUBY_OPTS=--1.9 in your environment, or you pass the --1.9 flag on the command line, JRuby will default to 1.8 mode, which means that you explicitly have to require 'rubygems' in main.rb before you load your gems.
How do I get ruby-debug to run under XP so that I can step through my Watir test scripts.
I am unable to "require" ruby-debug on Windows XP. All of the solutions I have seen refer to a Unix-based system running Rails. Here is my system profile:

ruby-debug has been broken with recent ruby versions for a very long time. Try the debugger gem instead. I've no idea if it works on Windows though.
try this
gem install ruby-debug --pre

Let me give you a hint. The name of your own program is clockwork.rb, and in it you do:
require 'clockwork'
See the problem?
you need to include the following in your clock.rb
require './config/boot'
require './coonfig/environment'
