WEBrick initialisation problem


#1

I am new to Ruby so I thought the best way to get into it would be to
follow the ONLamp “Rolling with Ruby on Rails” intro. I followed the
instructions to the letter and everything work just great, very
impressive:-).

A couple of days later when I went back to it I got the following
message when trying to start the WEBrick server.

U:\RoRProjects\cookbook>ruby script\server

U:\RoRProjects\cookbook>

I have tried totally uninstalling (ruby, rails, MySQL) and then
reinstalling but with no success. Obviously something has changed in the
environment that it is running in but I cannot recall anything that has
been done that would be of significance. Any ideas what could cause
this?

Any assistance would be gratefully received.

You probably have a WEBrick already running. Shut it down.
