How do I solve/debug "gem update" problem?

I used InstantRails 2.0 to install RoR on Win XP SP3. It brought rails 2.0.2 and I am having problems updating to rails 2.2.2

After initial installation I run “gem update—system” w/o a problem. However the subsequent “gem update rails” results in

ERROR: While executing gem … (Gem::InstallError) rails requires activesupport (= 2.2.2, runtime)

Trying to manually update activesupport by “gem update activesupport” results in

ERROR: While executing gem … (Gem::GemNotFoundException) could not find gem activesupport locally or in a repository

Other variations (“gem install rails—version 2.2.2”, "gem install activesupport", etc.) produce same errors.

A few more data points that may be helpful “gem -v” returns 1.3.1. "gem sources" outputs “RubyGems.org | your community gem host and "gem list—remote" output does include “activesupport (2.2.2)”

Any suggestions on how to resolve or at least debug the issue? I am a relative novice and am lost.

What does 'gem list --local' return? I presume you are doing this with administrative rights? Martin

Here is the output of "gem list --local"

I've had problems with upgrading gem in the past but they have involved gem itself and not running it once installed. Have a look at http://rubyforge.org/forum/forum.php?forum_id=28071 and try re-installing.

Does 'gem env' give you anything out of the ordinary? Martin

I am not sure what to look for in the output of "gem env" but here it is RubyGems Environment:   - RUBYGEMS VERSION: 1.3.1   - RUBY VERSION: 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]   - INSTALLATION DIRECTORY: C:/InstantRails2.0/ruby/lib/ruby/gems/1.8   - RUBY EXECUTABLE: C:/InstantRails2.0/ruby/bin/ruby.exe   - EXECUTABLE DIRECTORY: C:/InstantRails2.0/ruby/bin   - RUBYGEMS PLATFORMS:     - ruby     - x86-mswin32-60   - GEM PATHS:      - C:/InstantRails2.0/ruby/lib/ruby/gems/1.8      - C:/Documents and Settings/Leonid/.gem/ruby/1.8   - GEM CONFIGURATION:      - :update_sources => true      - :verbose => true      - :benchmark => false      - :backtrace => false      - :bulk_threshold => 1000   - REMOTE SOURCES:      - http://gems.rubyforge.org/

The only thing that appears a bit strange is the second line in GEM PATHS because it points to my documents folder while I expected RoR installation to be entirely self contained under C:/InstantRails2.0. I have already tried deleting everything (is that the right way to uninstall RoR?) and unzipped everything again from InstantRails-2.0.zip. Then I run "gem update --system" again and it upgraded rubygems to 1.3.1. I also observed that this gem update command added the second path to GEM PATHS (is it OK?). Now I am back hitting the same wall; still can not update rails and at a loss.

Thanks for trying to help, - LR
