Forum: Ruby Uncaught exception: cannot load such file --

There is an empty file called include_test.rb and a file test.rb which
includes include_test.rb
i.e. the content of test.rb:
require 'include_test.rb'

if I run:
ruby test.rb it gives following error:

Uncaught exception: cannot load such file -- include_test

Try

require './include_test.rb'

or

require_relative 'include_test.rb'

Is it so that require 'file_name' doesnt work with ruby 1.9.3 but works 
for 1.8.7?

I dont think that is the case as it is working fine on ubuntu, but not
on windows.

Ruby looks for include files that do not explicitly specify a path in
a series of paths. Some are hardcoded. To them you can add other paths
by including them in global variable "RUBYLIB".

From what I remember, ruby 1.8 included the current directory in the
hardcoded paths. This is not true anymore with 1.9. But if you specify
(in Linux)

export RUBYLIB='.'

then you will not need to specify the './' before your include file.
