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'm asked to look at some Ruby code. The developers run OSX, I'm on Windows. All is working fine on OSX, but I get an error with Scrypt 2.1.1.
I'm asked by Ruby to run: gem install scrypt -v '2.1.1' which results in an error.
When I do gem install scrypt -v '2.1.1' --platform=ruby it's quite the opposite and all the gem is installed.
Now when I recreate the GemFile or update it, I still get an error and it's again suggested to run gem install scrypt -v '2.1.1'.
The output I'm getting is:
Installing scrypt 2.1.1 with native extensions

I've looked and searched on Google and Bing, but nothing resulted in a solution.
Hope somebody in the community here can help me find the resolution.

gem install ffi --platform=ruby
gem install scrypt -v 2.2.1
Works for me.
I am running ubuntu 14.04.3 LTS on an Amazon EC2 instance. Any help resolving this error would be much appreciated.

I've been googling for hours and am still stuck. How to solve it?
There is a issue.

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 graphz.rb:1:in `<main>'
Does the script with require 'rsruby' have to be in the same directory as the rsruby.rb file?
