Having successfully gone through Bill W.'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
C:\InstantRails\rails_apps\ToDo>ruby script/generate model category
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:inrequire_gem_with_
require_gem' from ./script/../config/../config/environment.rb:57 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:inre
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:inre
Can somebody please point me as to what might be going on here?
Thanks in advance.
