Ruby – Relative path to your project directory


In my Ruby project I am using a mess of things like moving and editing files on several remote boxes and I really need something like a relative path to my root project directory. I have many processing folders which are used in many methods.

Right now I have paths hardcoded, but that makes me unhappy.

Best Solution

You can get current directory (directory of current file) with this


You can then join it with relative path to the root

File.join(File.dirname(__FILE__), '../../') # add proper number of ..

Or you can use expand_path to convert relative path to absolute.

ENV['BUNDLE_GEMFILE'] = File.expand_path('../../Gemfile', File.dirname(__FILE__))

Or you can calculate relative path between two dirs.

require 'pathname'; 
# => ../../..
