How to: Coffeescript-Compiling in Aptana

Question

I installed Aptana, and i want to try Coffeescript. When I try to "Compile and display JS" it won´t work - console shows:

....xyz.sh: line 3: coffee: command not found
....xyz.sh: line 3: pre: command not found

I don´t get it - how do i get it to run?

Thank you!

Edit:

Since yesterday I managed to get compass/sass running in Aptana (yeah!) - so i realized that my question might be wrong: Do i have to tell Aptana (Windows?) where to find the compiler?

Edit 2:

Realized: The problem is - how can this gem be installed (in Aptana if possible): via https://github.com/netzpirat/guard-coffeescript I get an error when installing the guard gem:

ERROR:  Error installing guard:
    The 'ffi' native gem requires installed build tools.

After trying some stuff here is a litte tutorial to setup compass and coffeescript for a project in Aptana:

(Info: I know very little about coding or ruby, so please be patient :) )

Create project ( i choose basic web template)

Terminal:

$ gem install compass
$ compass create myProject --using blueprint

check: http://compass-style.org/reference/blueprint/

You also have to setup some other stuff: I found this page and followed it through..

https://github.com/netzpirat/guard-coffeescript

Install bundle:

$ gem install bundle
$ bundle init //to create the gemfile

Install guard:

You need to install Ruby Devkit before - check this links:

http://rubyinstaller.org/downloads/

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

If you did so

$ gem install guard
$ gem install guard-coffeescript

I also installed a JS-Engine as recommended here:

https://github.com/netzpirat/guard-coffeescript#javascript-runtimes

$ gem install therubyrhino

For Coffeescript:

$ gem install coffee-script
$ gem install coffee-script-source

Then you have to edit the gemfile, mine looked like this:

# A sample Gemfile
source "https://rubygems.org"

# gem "rails"
group :development do
  gem 'guard'
end

group :development do
  gem 'guard-coffeescript'
end

group :development do
  gem 'therubyrhino'
end

run bundle

$ bundle

create guardfile

$ guard init

edit the guardfile

# A sample Guardfile
# More info at https://github.com/guard/guard#readme

guard 'coffeescript', :input => 'myProject/coffeescript', :output => 'myProject/javascript'

you can start the guard with

$ guard start

This worked for me! If you see any mistakes please let me know!
