[Instantrails-users] How to upgrade to rails 2.2.2

Thanks Rob. 
I should have mentioned in my original email that I did verify gem
version. Typing "gem -v" produces 1.3.1
Trying to follow your suggestion I typed "gem install update_rubygems"
and it resulted in
ERROR:  could not find gem update_rubygems locally or in a repository
"gem update rails" still does not work
I'd appreciate if someone can suggest additional investigative steps.

You do need to update your gems to at least 1.3 to get to Rails 2.2.2.
Please type gem -v at the command prompt in Instant Rails and see what
version it returns.  If it returns anything less than 1.3 then your gem
update failed.

If the gem update did not work then you will need to try something a bit
different.  Run these command from the Instant Rails command prompt:

gem install update_rubygems

If they run properly, typing gem -v again should give you the latest gem
and you can then update Rails.

Hi folks,

I  downloaded InstantRails 2.0 and installed it w/o a problem. That
brought rails 2.0.2. I would like to update rails to 2.2.2 so in Ruby
Console Window I typed "gem update-system" and it run w/o a problem (at
least I have not noticed one). However the subsequent "gem update rails"
results in

Updating installed gems
Updating rails
ERROR: While executing gem . (Gem::InstallError) rails requires
activesupport (= 2.2.2, runtime)

Trying to manually update activesupport by typing "gem update
activesupport" results in

Updating installed gems
Updating activesupport
ERROR: While executing gem . (Gem::GemNotFoundException) could not find
gem activesupport locally or in a repository

However I do see activesupport-2.2.2.gem listed in my browser pointed to

Any suggestions?
