Hi All,

When I run ruby script/server, I get the error message:

K:/\_Utilities/ruby186-26\_rc2/ruby/lib/ruby/gems/1.8/gems/rails-1.2.3/  
lib/initializer.rb:328:in `send': undefined method`session=’ for  
ActionController::Base:Class (NoMethodError)

Why did Ruby reference a rails-1.2.3 gem, rather than a 2.3.5 gem,  
since that’s what I specified in environment.rb:  
RAILS\_GEM\_VERSION = ‘2.3.5’ unless …  
and I have no system environment variable named RAILS\_GEM\_VERSION.

The error message is probably appropriate for the 1.2.3 Rails version  
because initializer.rb at line 328 is using meta-programming likely to  
produce the the variable “session=”.

However I specified Rails gem version 2.3.5, so the 1.2.3 version of  
initializer.rb should not have been invoked. And the 2.3.5 version of  
initializer looks fine on this score.

Could I have done something to cause this error?

TIA,  
Richard

Sorry, duplicate posting. (I forgot the title I last posted under and  
failed to flag it so I could find it when it received responses.)
