Rails - Jun 2006 - Newbie Four Days on Rails

Hi all,

Having successfully gone through  Bill Walton''s Tutorial
''Rollining with Ruby on [Instant] Rails''
I decided to tackle John McCreesh''s ''Four Days on
Rails'' Tutorial.

I changed the Rails version as recommended in the tutorial.

All went well until I entered the following command:-
ruby script/generate model category

I got:-

C:\InstantRails\rails_apps\ToDo>ruby script/generate model category
c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:149:in `activate'':
can''t activate act
ivesupport (= 1.0.4), already activated activesupport-1.3.1] (Gem::Exception)
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:37:in `require_gem_with_
options''
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:31:in
`require_gem''
        from ./script/../config/../config/environment.rb:57
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `re
quire''
        from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_suppo
rt/dependencies.rb:147:in `require''
        from c:/ruby/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/commands/generate.rb
:1
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `re
quire''
        from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_suppo
rt/dependencies.rb:147:in `require''
        from script/generate:3

Can somebody please point me as to what might be going on here?

Thanks in advance.

Stephen.

It looks like you''re using an older version of Rails, or, more
specifically, ActiveSupport.  I''m not sure how to fix that (can you
install older versions of rails and dependencies?), but I hope that''s
at least a starting point.  :/
