rails generate rspec: установить config/environment /development.rb:1: в `<top (обязательно)>': неопределенный метод`configure'

Question

Во -первых, вот мои версии:

Greg-Nowickis-MacBook-Pro:sample_app Greg_Nowicki$ ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-darwin13.1.0]
Greg-Nowickis-MacBook-Pro:sample_app Greg_Nowicki$ rails -v
Rails 4.0.4

Я следую руководству по Hartl Rails и устанавливаю rspec для тестирования. Я добавил gem 'rspec-rails' в мой gemfile, и когда я запускаю rails, генерируйте rspec: install, вот что я получаю:

Greg-Nowickis-MacBook-Pro:sample_app Greg_Nowicki$ rails generate rspec:install

Вот мой гемфайл:

source 'https://rubygems.org'
ruby '2.0.0'


gem 'rails', '4.0.4'

group :development, :test do
  gem 'sqlite3', '1.3.8'
  gem 'rspec-rails', '~> 3.0.0.beta'
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
end

gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

а вот конфиг / environment / development.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true
end

Есть мысли о том, что это может быть? Я пошел дальше и обновил rspec-rails до последней версии - мысли?

Answer 1

В config/environment /development.rb:

менять

Rails.application.configure do 

в

SampleApp::Application.configure do

Я проверил пару своих приложений, и вот формат, который у меня есть.

Answer 2

Смена development.rb мне совсем не помогла.

Однако, что мне помогло, так это:

рвм 2.0.0

ДО создания приложения с

$ rails new first_app

Обратите внимание, что версия Gemfile была 2.0.0, а не 2.1.1, что было у меня изначально, поэтому сопоставьте версии ruby, прежде чем создавать свое приложение.

Не уверен, почему это важно.

Answer 3

Попробуйте использовать другую версию rspec, заменив бета-версию этой версией в своем Gemfile: gem 'rspec-rails', '>= 2.14'

РЕДАКТИРОВАТЬ: вы бежали bundle install а также rails generate rspec:install прежде чем пытаться запустить rspec?
