Is there a standalone Ruby (and Rails) solution that can be run from a flash drive?

In the near future, I can teach the Ruby programming class to students at art college. This is a safe assumption that students have little or no programming experience. The class will be taught in a computer lab, but they do not have any administrative rights on lab computers.

Ideally, I would like students to be able to run Ruby from a flash drive both in the lab and on their computers at home. Even better, if this can be done relatively transparently on both a Mac and a Windows PC (I suppose Linux users probably know how to set up Ruby anyway). And even better if they can run Ruby on Rails and / or install gems using the Ruby installation on a flash drive.

Is this completely unrealistic or is there an easy way to do this? These will be non-programmers, art students, so the less tuning at their end, the better.

Edit:

I should have mentioned that I know of several one-click installations for Ruby and Rails. I guess I'm wondering if there is a way that I can give students an already configured installation that runs away from the flash drive and allows them to run Ruby scripts and possibly even install gems.

To get started, you'll need two copies of Ruby on your USB drive: one for Windows and one for Mac OS X.

Then you need to create a script in each to add Ruby to the path and open a terminal.

I would build it like this:

  • ruby
    • window
      • bin, lib, etc.
      • start.bat
    • mac.
      • bin, lib, etc.
      • start.sh

Window

Content start.bat

@echo off
set PATH=%CD%\bin;%PATH%
start cmd

Create shortcut for start.batwith working directoryruby/windows

Mac OS X

start.sh ( script)

...

script.
