I just used the code below to install rsruby on my Mac:
sudo gem install rsruby
Then I tried to load rsruby in my Ruby code:
require 'rsruby'
When running this I get this error:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- rsruby (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from graphz.rb:1:in `<main>'
Does the script with require 'rsruby' have to be in the same directory as the rsruby.rb file?

It looks to me like you have a require 'colorize' in your code, but the gem colorize is not installed. You can install the gem by running:
gem install colorize
I assume you have gem installed. Otherwise you need to install it as well.
I am running OS X 10.11.6 and I installed Jekyll (using the already existent ruby on my system) by the recommended method: sudo gem install -n /usr/local/bin/ jekyll.
I can happily run jekyll on my system so I made a new site by running jekyll new TestSite which successfully executed.
However, this is where it stops working: if I cd into the site directory and run any jekyll command I get the following error:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

Any ideas how to get it working?
It seems you don't have bundler gem. Try
gem install bundler
Trying to install em-irc, got that:

I am trying to run a ruby script to rename some files but I get the following error:
Eccleshall$ ruby rename.rb
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- ftools (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from rename.rb:45:in `<main>'
Thanks for the help.
Change to script to say:
require "fileutils"
instead of
require "ftools"
ftools has been deprecated.
I'm new to Ruby and just installed Ruby for Windows.
I want to use the mechanize library (https://github.com/tenderlove/mechanize) and so I'm following the guide at https://github.com/tenderlove/mechanize/blob/master/GUIDE.rdoc.
On the Windows cmd line, I installed mechanize by using the cmd "gem install mechanize".
When I run the following code:
require 'rubygems'
require 'mechanize'
agent = Mechanize.new
I get the error:
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- net/http/digest_auth (LoadError)
from <internal:lib/rubygems/custom_require>:29:in `require'
from C:/Ruby192/lib/ruby/1.9.1/mechanize.rb:5:in `<top (required)>'

from helloworld.rb:2:in `<main>'
Anybody know what's going on?
It seems that some dependencies are missing. Try to install the net-http-digest_auth gem.
gem install net-http-digest_auth
If that solves this problem and another (related) pops up, it's probable that you are missing the net-http-persistent gem. If that's the case, you know what to do! Just install it too.
