Dear all,

I was struggling with a problem. I have a product class and a test file  
under Merchant folder. when i run my product class it shows following  
error.

c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem\_original\_require': no such file to load -- builder (LoadError)  
&nbsp;&nbsp;from c:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`require'  
&nbsp;&nbsp;from product.rb:2

I need to set path like set RUBYLIB = ""

i didnt got how to set the path and in which file i have to set or in  
shell prompt? how to set path?

Could any one help me to solve this problem of setting path.

Thanks in advance

Regards,  
Martin

maybe gem install builder?  
if not maybe google for 'rubygems path' and 'RUBYLIB environment variable'

There are basically three possibilities let us say your library is here:  
/lib/mylibs/mylibrary.rb  
(1)  
setting the variable  
export RUBYLIB="/lib/mylibs/${RUBYLIB:-""}"  
(2)  
using a command line option  
ruby -I/lib/mylib myprog.rb  
(3)  
adjust your $: inside your ruby program  
$:.unshift File.join( %w{ /lib mylib } )
