Hey all,

I am not sure if this is a Leopard on Ruby problem or some other quirk  
(or  
maybe I am just horribly overlooking something) but…:

Macintosh:manav mbp$ irb

> > require ‘yahoofinance’  
> > =\> true
> 
> > Macintosh:manav mbp$ cat yahoo\_test.rb  
> > require ‘yahoofinance’  
> > Macintosh:manav mbp$ ruby yahoo\_test.rb  
> > yahoo\_test.rb:1:in `require’: no such file to load – yahoofinance  
> > (LoadError)  
> > from yahoo\_test.rb:1

i.e. irb can see the gem but ruby can’t…  
Any ideas?

Cheers,  
Peter

your ~/.irbrc has:

require “rubygems”

Probably your .irbrc requires rubygems while your script doesn’t.

HTH,
