未定义的方法infer_base_class_for_anonymous_controllers

Question

好了，这是RoR上的一个新功能，尝试在一个骨架应用上运行spork，会得到以下错误：

Using RSpec, Rails

undefined method `infer_base_class_for_anonymous_controllers=' for #<RSpec::Core::Configuration:0x007fe0b5672850> (NoMethodError)

我的GemFile如下：

 gem 'rails', '4.0.2'

 # Use postgresql as the database for Active Record
 gem 'pg'


 ....
 group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
 gem 'sdoc', require: false
end

group :development, :test do
 gem 'capybara',     '2.1.0'
 gem 'rspec-rails'
 gem 'activeadmin', github: 'gregbell/active_admin'
 gem 'database_cleaner'
 gem 'spork-rails', '4.0.0'
 gem 'guard-spork', '1.5.0'
 gem 'childprocess', '0.3.6'

end

和我的spec_helper：

 RSpec.configure do |config|
   ....
 config.infer_base_class_for_anonymous_controllers = false
 config.order = "random"
 config.include Capybara::DSL

Answer 1

rspec-rails提供了infer_base_class_for_anonymous_controllers方法。我的猜测是您在调用RSpec.configure之前并不需要它。

Answer 2

我有其他的问题，为了解决它，我搬到

config.infer_base_class_for_anonymous_controllers

从spec_helper.rb到rails_helper.rb
