Failed WATIR installation Server 2003 - ruby

Question

I had to rebuild my box and I currently am unable to install Watir.
gem install watir
ERROR: Error installing watir:
activesupport requires Ruby version >= 1.8.7.
Which would be fine if Watir was able to use Ruby 1.8.7 . I am using
ruby -v
ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]
gem -v
1.3.7
I am not sure when this started to occur, but the documentation on the site is lacking.

Answer 1

On Windows XP (Professional, Version 2002, Service Pack 3, fully pathched) I have installed ruby186-26.exe from RubyForge, as suggested at watir.com/installation.
C:\>ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]
C:\>gem env
RubyGems Environment:

- INSTALLATION DIRECTORY: c:/ruby/lib/ruby/gems/1.8
- GEM PATH:

- REMOTE SOURCES:

Automatic RubyGems update did not work:
C:\>gem update --system

ERROR: While executing gem ... (Gem::RemoteSourceException)

I have downloaded rubygems-update-1.3.7.gem from RubyForge, copied it to the folder where I have command prompt open (C:\ in this example) and installed:
C:\>gem install rubygems-update-1.3.7.gem
Successfully installed rubygems-update, version 1.3.7

To make sure I have the latest RubyGems:
C:\>gem env

Now Watir did not want to install:
C:\>gem install watir
ERROR: Error installing watir:
activesupport requires Ruby version >= 1.8.7.
I have installed activesupport-2.3.8 as suggested by Charley Baker, and I was able to install Watir:
C:\>gem install activesupport --version="2.3.8"
Successfully installed activesupport-2.3.8

Answer 2

I had a similar issue just now and thought I would add a comment to this issue. Our dev vm's are currently running windows 7, therefore I needed to run my command prompt as administrator for the gem installation to work correctly.
