Ruby cannot load such file --ftools (Load Error)

Question

I'm a complete Ruby newbie and all I want to do is just run a legacy ruby script (that too an open source one by Erik Veenstra). I have a Windows batch script that runs it basically that I am trying to execute. I installed Ruby on my computer, allowed it to set paths, and I tried to run it and here's the error I got:

I:/2011/devl/3rdparty/ruby/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- ftools (LoadError)

Appreciate any ideas on how to resolve this! If it helps I can post the source Ruby code.

Answer 1

use

require "fileutils"

instead because ftools is not supported with ruby-1.9.x

Answer 2

Apparently, the source code I had is a lot older and even after getting the latest version, it had issues. But knowing that it worked at some point, I proceeded to install an older version of Ruby on Windows (1.8.7-p358) and everything works fine then and I was able to build and get my executable. Anyway, not the most elegant solution. But if anybody knows of a fix for rubyscript2exe with the latest Windows version of Ruby, please reply. Thanks.
