This is the full stack after installing with bundler and running rails g impressionist:

found temporary solution:

# add to application.rb at the top
impressionist_dir = Gem::Specification.find_by_name('impressionist').gem_dir
require File.join(impressionist_dir, '/app/controllers/impressionist_controller.rb')

Enjoy :)
