rails 生成 rspec:install config/environments/development.rb:1:in `<top (required)>': 未定义的方法 `configure' [英] rails generate rspec:install config/environments/development.rb:1:in `<top (required)>': undefined method `configure'

问题描述

首先，这是我的版本:

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

我正在关注 Hartl Rails 教程并安装 rspec 进行测试.我已经将 gem 'rspec-rails' 添加到我的 gemfile 中，当我运行 rails generate rspec:install，这就是我得到的:

I'm following the Hartl Rails tutorial and am install rspec for testing. I have added gem 'rspec-rails' to my gemfile and when I run rails generate rspec:install, this is what I get:

这是我的 gemfile:

Here is my gemfile:

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

这里是 config/environments/development.rb

and here's config/environments/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

对这可能是什么有任何想法吗?我继续将 rspec-rails 更新到最新版本 - 想法?

Any thoughts on what this may be? I went ahead and updated rspec-rails to the latest version - thoughts?

推荐答案

在 config/environments/development.rb:

In config/environments/development.rb:

改变

Rails.application.configure do 

到

SampleApp::Application.configure do

我检查了几个应用程序，这就是我拥有的格式.

I checked a couple of my applications, and thats the format I have them.
