Understanding Ruby's load paths

Question

I\'m a little confused about why my project can\'t load the files it needs, it\'s a really simple project tree:

processor/
  bin/
  lib/
    processor.rb
            


        

Answer 1

Ruby's $LOAD_PATH will not include your lib directory by default (even though that's where the file you're running is located).

You can either tell the ruby interpreter to include it:

ruby -Ilib lib/processor.rb

Or you can add the lib folder to the load path:

$LOAD_PATH.unshift(File.dirname(__FILE__))
require  'processor/mapper'
