Ruby Install/Init Not Finding dk.rb -

-

i'm trying download/install ruby on win7(i'm new ruby).

i went url: http://rubyinstaller.org/downloads/ , downloaded version "ruby 1.9.3-p545" installed following folder/directory: c:\rubydevkit\ (no spaces in folder name).

i'm getting following error when try init step:

c:\rubydevkit>ruby dk.rb init ruby: no such file or directory -- dk.rb (loaderror)

i ran on command line:

c:\rubydevkit>ruby -v ruby 1.9.3p545 (2014-02-24) [i386-mingw32]

so have ruby installed , i'm in correct directory(per link:loaderror when installing ruby devkit)

i tried , got same error:

c:\rubydevkit>chcp 1252 active code page: 1252

i have aptana v3, build 3.4.2.201308081805 installed(but no other versions of ruby). can't find acutal file dk.rb anywhere through windows explorer/cmd line.

i'm not sure ruby , running, getting past "init" step.

edit: in aptana ide -> terminal typed:

$ gem install ruby-debug-ide --platform=ruby

and got back:

fetching: ruby-debug-ide-0.4.22.gem (100%) error:  error installing ruby-debug-ide:     'ruby-debug-ide' native gem requires installed build tools.  please update path include build tools or download devkit 'http://rubyinstaller.org/downloads' , follow instructions @ 'http://github.com/oneclick/rubyinstaller/wiki/development-kit'

also add(from cmd line:

c:\rubydevkit\bin>gem -v 1.8.28

you need devkit build native c extensions.

in case not sound have downloaded devkit separately. secondly ensure devkit , ruby matching architecturally, of system running on (x86/64).

consider following tutorial: http://www.waydotnet.com/2010/02/12/rmagick-on-ruby-1-9-1-i386-mingw32-work-d/
