It's telling you that there is a syntax error in the way you  
specified the filename. I don't use Windows so I can't test exactly,  
but it looks like enclosing the filename in quotes might help.  
Alternatively substitute backslash for forward slash. E.g:

b "c:\users\jbucaran\desktop\demo2.rb":1

Also, don't type in this line:

Set breakpoint 1 at c:\users\jbucaran\desktop\demo2.rb:1

That is output from the debugger.

As to your question about whether it is necessary to run rubygems to  
use the debugger then the answer is 'it depends'. If your script uses  
gems then it is necessary, otherwise it isn't. I don't know anything  
about environment variables in Windows, so someone else will have to  
help you there. I would have thought that you should be able to get  
some information from Google.
