"wrong constant name" Error when using Turnip with Spork - ruby-on-rails

Question

My Turnip test is working normally, but does not work when using spork.
I debugged with pry and I found that a missing User(class constant) causes the error.
What should I do to fix?
# working (good)
bundle exec rspec spec/acceptance/features/*
# not work (bad)
bundle exec rspec spec/acceptance/features/* --drb
Here is the error when I run with the --drb option.
Failure/Error: Give a user logged in:
NameError:
wrong constant name #<Module:0x007fd40a19c680>
# spec/acceptance/steps/user_steps.rb:8:in `block (2 levels) in <module:UserSteps>'
# spec/acceptance/steps/user_steps.rb:7:in `each'
This is my spec_helper.rb.
require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'
Spork.prefork do
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/dsl'

config.before(:suite) do

end

end
config.before(:each, js: true) do
headless = Headless.new
headless.start
end
end
end
Spork.each_run do
# This code will be run each time you run your specs.
end
This is user_steps.rb.
1. require_relative 'helper_steps'
2.
3. module UserSteps
4. include HelperSteps
5.
6. step 'users are registered :' do |table|
7. table.hashes.each do |row_hash|
8. create(:user, class_params_by_row_hash(User, row_hash))
9. end
10. end
11. end

I'm not sure why this problem occurs, but you can prevent it from happening. If you're wrapping your steps in modules, you don't need to pass the true wrap parameter to load. Change:
Dir.glob("spec/**/*steps.rb") { |f| load f, true }
to:
Dir.glob("spec/**/*steps.rb") { |f| load f }
This prevents this error for me.
