Rails uninitialised hằng số ActiveSupport :: Autoload (NameError)?

Question

Tôi đang ở chương 3 của hướng dẫn của Michael Hartl và tôi bị kẹt ở phần kiểm tra. Ban đầu nó có vấn đề của một Rails liên tục uninitialised (NameError) nhưng sau khi thêm

require 'rspec/rails' 
require 'active_support' 
require 'active_support/deprecation' 
require 'activerecord-nulldb-adapter' 

đến tập tin spec_helper.rb, có phải là vấn đề mới này với ActiveSupport liên tục uninitalised :: Autoload (NameError).

Kèm theo là các lỗi:

Hãy thử thay đổi trật tự từ

require 'rspec/rails' 
require 'active_support' 
require 'active_support/deprecation' 
require 'activerecord-nulldb-adapter' 

Để

require 'active_support' 
require 'active_support/core_ext' 
require 'active_support/deprecation' 
require 'rspec/rails' 
require 'activerecord-nulldb-adapter'
