undefined method `infer_base_class_for_anonymous_controllers=' for # (NoMethodError)

问题

I'm currently on Chapter 7 of Hartl's Tutorial, and every time I run

bundle exec rspec spec/

the following results:

/Users/siciliana/sample_app/spec/spec_helper.rb:31:in `block in <top (required)>': undefined method `infer_base_class_for_anonymous_controllers=' for #<RSpec::Core::Configuration:0x007f7fb3a62b80> (NoMethodError)

Can someone please explain what is happening here to an absolute newbie?

spec_helper.rb :

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

#
RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"

end

I was getting the same error (although not following the tutorial).

I believe this setting requires 'rspec/rails'

My solution was to move the line

config.infer_base_class_for_anonymous_controllers = # whatever

From spec_helper.rb to rails_helper.rb.
