Hello,

I have rails-2.0.2 and rails-2.1.0 installed via gem. I want to  
generate a rails 2.0.2 app, how do I do that? I tried the following  
command and got the following error…

$ ruby /Library/Ruby/Gems/1.8/gems/rails-2.0.2/bin/rails myapp  
/Library/Ruby/Gems/1.8/gems/rails-2.0.2/bin/…/lib/rails\_generator/  
options.rb:32:in `default_options': undefined method`write\_inheritable\_attribute’ for Rails::Generator::Base:Class  
(NoMethodError)  
from /Library/Ruby/Gems/1.8/gems/rails-2.0.2/bin/…/lib/  
rails\_generator/base.rb:90  
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/  
usr/lib/ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/ usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in`require’  
from /Library/Ruby/Gems/1.8/gems/rails-2.0.2/bin/…/lib/  
rails\_generator.rb:34

`require’  
from /Library/Ruby/Gems/1.8/gems/rails-2.0.2/bin/rails:13

Thanks for the help.
