RSpec 3.1 undefined method `feature' for main:Object - ruby-on-rails

Question

I´m going through the rather painful upgrade to RSpec 3.1. I have several feature specs which worked in RSpec 2.99 that raise:
undefined method `feature' for main:Object
I noticed that I have to use RSpec.describe in my other specs since they are are no longer attached to the main object. What would the equivalent call for feature be?
In my features I require 'rails_helper'
require 'rails_helper'
feature 'Facebook Authentiation' do
...
end
spec/rails_helper.rb
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require 'spec_helper'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rails/application'
# Add additional requires below this line. Rails is not loaded until this point!
ActiveRecord::Migration.maintain_test_schema!
RSpec.configure do |config|
# 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 = false
# RSpec Rails can automatically mix in different behaviours to your tests
# based on their file location
config.infer_spec_type_from_file_location!
end
spec/spec_helper.rb
#

RSpec.configure do |config|
# rspec-expectations config goes here. You can use an alternate
# assertion/expectation library such as wrong or the stdlib/minitest
# assertions if you prefer.
config.expect_with :rspec do |expectations|
# This option will default to `true` in RSpec 4. It makes the `description`
# and `failure_message` of custom matchers include text for helper methods
expectations.include_chain_clauses_in_custom_matcher_descriptions = true
end
# rspec-mocks config goes here. You can use an alternate test double
# library (such as bogus or mocha) by changing the `mock_with` option here.
config.mock_with :rspec do |mocks|
# Prevents you from mocking or stubbing a method that does not exist on
# a real object. This is generally recommended, and will default to
# `true` in RSpec 4.
mocks.verify_partial_doubles = true
end
# These two settings work together to allow you to limit a spec run
# to individual examples or groups you care about by tagging them with
# `:focus` metadata. When nothing is tagged with `:focus`, all examples
# get run.
config.filter_run :focus
config.run_all_when_everything_filtered = true
# Limits the available syntax to the non-monkey patched syntax that is recommended.

# Seed global randomization in this process using the `--seed` CLI option.

Answer 1

It looks like your forgot to require capybara at your spec/rails_helper.rb
require 'capybara/rspec'
Also you can try to remove this line:
config.disable_monkey_patching!
Or check if capybara adds feature method to Rspec namespace:
RSpec.feature "My feature" do
...
end

Answer 2

I've faced the same issue with rails 4.2 even though I've had
require 'capybara/rspec' in rails_helper.rb
and
require 'spec_helper' in feature spec.
Solution is to require 'rails_helper' in feature spec as well.

Answer 3

In my case the problem was that I had the
require "spec_helper"
line lower in rails_helper.rb.
When I moved it at the top, everything went back to normal.
For your reference, my rails_helper.rb first lines now are:
require "spec_helper"
ENV["RAILS_ENV"] ||= "test"
require File.expand_path("../../config/environment", __FILE__)
abort("The Rails environment is running in production mode!") if Rails.env.production?
require "rspec/rails"

Answer 4

I had to use the following in my problem which is a combination of previous answers:
spec/features/visitors/navigation_spec.rb
require 'spec_helper'
require 'capybara/rspec'
RSpec.feature 'Navigation links', :devise do
...
end
spec/rails_helper.rb
require 'capybara/rspec'
spec/spec_helper.rb
config.disable_monkey_patching = false
