Hi everybody,

I’ve got a strange problem and hope this is the right place for it.  
I’ve recently installed a new gem for ruby, called ‘rsruby’ (but it  
shouldn’t matter I think which one it is).

The problem is the following:

irb(main):001:0\> require ‘rsruby’  
LoadError: no such file to load – rsruby  
from (irb):1:in `require’  
from (irb):1

I just can’t include it. BUT when I move directly into the gem’s  
folder, it works just fine. In other words, when I open the ruby shell  
from within /usr/lib/ruby/gems/1.8/gems/rsruby-0.5.1/lib the output is

irb(main):001:0\> require ‘rsruby’  
=\> true

as it should and I can use the gem without any problems.  
Any ideas where this could come from? I hope this is really a ruby  
issue and not a server (debian) issue.

Thanks in advance,

Dennis S.

you need to: require ‘rubygems’
