Zeus returning warning for a parallel rspec tests

Question

I'm trying to make my rails development process faster with zeus. So, I installed zeus & parallel_tests gems. All of them working good, but when I'm trying to connect this to gems via zeus-parallel_tests gem, I get this annoying warnings every operation. What can I do to avoid this warnings?

$ zeus parallel_rspec spec/
4 processes for 17 specs, ~ 4 specs per process
Warning: Specifying a Rails environment via RAILS_ENV has no effect for commands run with zeus.
Warning: Specifying a Rails environment via RAILS_ENV has no effect for commands run with zeus.

You need to unset your RAILS_ENV environment variable, to make zeus stop complaining.

You can achieve this by temporarily unsetting it for the zeus command:

$ RAILS_ENV='' zeus parallel_rspec spec/

If you want to set the environment variable permanently, you can export it from your .profile or .bash_profile:

$ echo RAILS_ENV='' >> ~/.profile'

To make your environment pick up the change, you will need to "source" it: $ source ~/.profile.
