What does bundle install --without production do?

Question

Ive seen people using this and used it myself as told to do so. I just dont have a real grasp as what it actually does. I understand fully the bundle install part,

Answer 1

If you have a group inside your Gemfile like

group :production do
    gem 'whatever'
end

Then when you run your bundle command on your development machine, it won't install the gems intended for use in your production environment. Basically only installing the gems you need in development on your development machine.
