This error occurred while loading the following files:
   scrubyt

I think the problem is with--- require 'scrubyt' in my code

gem list --shows scrubyt <0.3.4> is installed

and forum of this scrubyt (www.agora.scrubyt.org) also not working.

can anyone knows how to solve this. I am already wasted lots of time on
this.
