uninitialized constant Tidy

[Harry]

Hi,

I was trying to start my app, but always got this error:

c:/user/software/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_supp
ort/dependencies.rb:266:in `load_missing_constant': uninitialized
constant Tidy
(NameError)
from
c:/user/software/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/li
b/active_support/dependencies.rb:452:in
`enumerations_original_const_missing'
from
/script/../config/../vendor/plugins/enumerations_mixin/lib/active_
record/virtual_enumerations.rb:63:in `const_missing'
from
c:/user/software/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/li
b/active_support/dependencies.rb:464:in `const_missing'
from ./script/../config/../config/custom_environment.rb:26

I installed tidy gem and copied the tidy.dll to windows and ruby root
directories, but still have this error.

Anyone knows how to fix it?

Thanks,
Harry
