Question

I have a local development machine which has started to give me the following error on starting up the Rails server:

    C:/Software/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active_support/i
nflector.rb:404: uninitialized constant ActiveSupport::CoreExtensions::String (N
ameError)   

    from C:/Software/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:
31:in `gem_original_require'
        from C:/Software/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:
31:in `require'

No Rails specific updates have been made on this machine, only automatic Windows updates.

Anyone have a clue on this? I cannot upgrade to Rails 2.3.5.

Thanks!

Just to let everyone know. The error was due to a power outage that caused the computer to shut down incorrectly, and which corrupted some of the files on the machine.

Uninstalling every Rails version and dependencies, and reinstalling them fixed the issue (although uninstalling just the version that was being used could also have done the trick).
