I'm currently developing a Rails 2 project that I'd like to migrate
across to Rail 3. However I'm having real trouble in the first place
getting Rails 3 to work straight out of the box with a blank project.
Initially I tried getting this working a JRuby 1.5 snapshot & then 1.4.
I've now been trying the same with Ruby 1.9.1-p378-rc2 from
RubyInstaller with the same results.
The error:
Upon executing "ruby script\rails server" (rails server doesn't work in
Windows. Running Win7 btw) I always get the following error...
C:\Users\Phil Ostler\Desktop\Project\Rails>ruby script\rails server
C:/Users/Phil Ostler/Desktop/Project/Rails/config/application.rb:9:in
`<module:Rails>': superclass mismatch for class Application (TypeError)
from C:/Users/Phil
Ostler/Desktop/Project/Rails/config/application.rb:8:in `<top
(required)>'
from
C:/Ruby19/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta/lib/rails/co
mmands.rb:36:in `require'
from
C:/Ruby19/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta/lib/rails/co
mmands.rb:36:in `<top (required)>'
from script/rails:10:in `require'
from script/rails:10:in `<main>'
I've tried using the latest gems as well as following any guides I could
find and matching the gem versions they used but always get the same
result.
Current local gem list:
*** LOCAL GEMS ***

I've googled this and vaguely understand the error but don't know how to
go about fixing it. I get the feeling this might not be my setup and
more a gem that's breaking Rail 3 but that could be miles off the mark.
Any suggestions?
Cheers, Phil
