I'm getting the following error when I try to run an rspec test:

/srv/offerme/spec/requests/static_pages_spec.rb:13: undefined method `visit' for #<Class:0xb3436684> (NoMethodError)
from /var/lib/gems/1.8/gems/rspec-core-2.11.1/lib/rspec/core/example_group.rb:238:in `module_eval'

from /usr/local/bin/rspec:19

The file I get this error in looks like this (spec/requests/static_pages_spec.rb) :

require 'spec_helper'

describe "StaticPages" do
include Capybara::DSL
  describe "GET /static_pages" do
    it "works! (now write some real specs)" do
      # Run the generator again with the --webrat flag if you want to use webrat methods/matchers
      get static_pages_index_path
      response.status.should be(200)
    end 
  end 
  describe "Home page" do
    visit 'static_pages/home'
    page.should have_content('OfferMe')
  end 

end

My spec_helper.rb file looks like this:

# 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'
require 'capybara/rspec'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

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"
  config.include Capybara::DSL
end
module ::RSpec::Core
class ExampleGroup
include Capybara::DSL
include Capybara::RSpecMatchers
end
end

And, finally, my Gemfile looks like this:

source 'https://rubygems.org'

gem 'rails', '3.2.7'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
end

group :test do
  gem 'capybara'
end

gem 'json'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.4'
  gem 'coffee-rails', '~> 3.2.2'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
  gem 'twitter-bootstrap-rails'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug'

gem 'therubyracer', '0.10.1'
gem 'libv8'
gem 'webrat'

I have seen this GitHub issue and have tried some of the workarounds as well as looked at some other StackOverflow questions pertaining to the similar issue (that's why some of the code looks redundant/hacky). However, none of them have worked yet. Please help!

更新：

问题是你在visit一个it块之外调用，这里：

describe "Home page" do
  visit 'static_pages/home'
  page.should have_content('OfferMe')
end

将这些中间线包裹在一个it块中：

describe "Home page" do
  it "has a homepage" do
    visit 'static_pages/home'
    page.should have_content('OfferMe')
  end
end

那应该行得通。

原始答案：

我可能是错的，但我相信你必须在 Gemfile 的测试和开发部分都包含 capybara。

尝试将 Gemfile 的该部分更改为：

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
  gem 'capybara'
end

这是一个旧帖子。我有同样的问题。我想我分享我的解决方案。在我的 Gemfile 中，我有

group :test do
  gem 'capybara'
end

并且visit在正确的位置但是我遇到了同样的错误。所以这就是我所做的。我在 Gem 上运行了更新，现在一切都很好。

bundle update capybara

希望这对某人有所帮助。
