Error on start when using Spork and Guard

Question

Here's the problem. When added the Guard gem everything was fine when I was calling Guard. When I added Spork, I get the following error that doesn't affect testing my tests but it brings it up every time I try to restart Guard.

19:01:28 - INFO - Guard uses TerminalTitle to send notifications.
19:01:28 - INFO - Starting Spork for RSpec
19:01:28 - ERROR - Guard::Spork failed to achieve its <start>, exception was:

You haven't provided a lot of information. However, take a look at this rails cast. railscasts.com/episodes/285-spork , follow it step by step, and you should have no problem running Guard with spork. — Andrew Wei
What other information do you need? I had a look at the RailsCast; it was more or less based upon it that I added spork and guard — PericlesTheo
After adding spork, you ran bundle install? Mind posting your guardfile also — clang1234

That’s a known issue in guard-spork and you can either use the previous version of ChildProcess by adding:

gem 'childprocess', '0.3.6'

To your Gemfile or try the guard-spork master branch, which has fixed the issue by adding the following to your Gemfile:

gem 'guard-spork', :github => 'guard/guard-spork'
