Does anyone know why an application would work on Mac and not on Windows? When I attempt to start WEBrick it tries to start and then it just hangs. There is no error message. Is there a way to debug to get further information? Thanks ---

Ruby on windows seems to have trouble with those… \_Kevin ---

I’ve had a lot of problems with both WEBrick and the bundled Apahce/SCGI server not starting or hanging using that. ---

I did try InstantRails, but the same results. CMD prompt opens to start Mongrel and then crashes. No error messages. Is there a system log that would offer more details or does it just die? ---

Sound likes your mac has the rcss gem installed and the windows machine doesn’t Fred ---

I read some of the other posts which suggest tabs can also be a problem in Windows. Hopefully a best practices document will be created to remind developers of those known issues moving from one OS to another. After replacing the tabs with spaces in the .rb, I was able to get to a new set of error messages when i started WEBrick. It turns out there are two gems used by the application that are not included with the RoR Windows installation: ``` * rcss (gem install rcss) * redcloth (gem install redcloth) ``` It works now 🙂 Thanks All!

Thanks Curt, ## I ended up trying it both with ruby script/console for WEBrick and your suggestion with Instant Rails and I come back to the same error message: ## c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `gem_original_re quire': no such file to load -- rcss (LoadError) from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in`re quire’ from ./script/…/config/…/config/environment.rb:9 from c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `re quire' 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:in `load_modules' from c:/ruby/lib/ruby/1.8/irb/init.rb:21:in`setup’ from c:/ruby/lib/ruby/1.8/irb.rb:54:in `start’ from c:/ruby/bin/irb.bat:20 Thanks Again
