Console load failure on windows

I had a very odd problem recently that manifested itself like this…

C:\rails_apps\cookbook>ruby script/console
Loading development environment.
require__': no such file to load -- ./script/../config/ ../config/environment (LoadError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:21:inrequire’
from c:/ruby/lib/ruby/1.8/irb/init.rb:252:in load_modules' from c:/ruby/lib/ruby/1.8/irb/init.rb:250:inload_modules’

just never noticed it before because this wasn’t my main development

Deleting the key fixes the problem and restores the console (and other

There. Now the only other person in the world who will do this can find
the solution. I feel better now.


Hey, thanks soooooooo much for this…

I am that ‘other person’

I have searched lots and lots for a solution and was actually going to
post a question on the board but decided to search and see if anyone
else had this problem.

Thanks again for posting this becuase I’ve reinstalled Ruby twice for
this, as well as rails and all the dependencies. I was considering
reinstalling my OS too!!! Thanks again. If you’re ever in Glasgow,
Scotland I’ll buy you a pint.
