Ruby gems require issue

Question

I am very new ruby all I am trying to do is actually use a open source code provided in google code to get stackoverflow data to mysql tables. Its in ruby and can be found at the following location (http://geeqe.googlecode.com/svn/trunk/scripts/load.rb). First few lines of code as follows:

require 'rubygems'
require 'libxml'
require "mysql"
require "pp"

include LibXML

Prior to this installs rvm, then executed rvm install 1.9.3, rvm install jruby

But when I try to execute ruby load.py I get the following error I am not really sure what to make out of since my limited knowledge of ruby.

/Users/mac/.rvm/rubies/ruby-1.9.3-p374/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- libxml (LoadError)
    from /Users/mac/.rvm/rubies/ruby-1.9.3-p374/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from load.rb:2:in `<main>'

Answer 1

Just repeating the comment that I made above: "Did you install libxml? Try running 'gem install libxml-ruby'."

Answer 2

You are also missing the mysql gem. $gem install mysql
