Hi Steve, Thanks for your response.
I solved one of my problems: the "rack(1.0.0 not ~> 1.0.1)" error: following the advice on another forum, I executed: gem install rack -v 1.0.1 That leaves another problem: I'm running "ruby script/server" in the directory, RTS containing a Rails implementation that includes the statement "RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION" in the file "RTS\config\environment.rb" file. I have no RAILS_GEM_VERSION environment variable among WindowsXP's environment variables. The server script gives me 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 it reference a rails-1.2.3 gem, rather than a 2.3.5 gem, since that's what I specified in environment.rb: On Feb 19, 6:53 pm, Steve Klabnik <[email protected]> wrote: > You'd have been fine with 2.3.5 if you'd have rack 1.0.1 installed. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
