Rails uninitialised constant ActiveSupport::Autoload (NameError)?

Question

I am at chapter 3 of Michael Hartl's tutorial and I am stuck at the testing part. Initially it had the problem of an uninitialised constant Rails (NameError) but after adding

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

to the spec_helper.rb file, there is this new problem with uninitalised constant ActiveSupport::Autoload (NameError).

Attached is the error:

Try changing the order from

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

To

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

Hi thank you for your comment, I've tried it and it now gives me another error, uninitialised constant ActionView::Template::Handlers::ERB::ENCODING_FLAG (NameError). Do you have any idea as to what is this? – Hanzawa Naoki Jun 19 '14 at 13:48
solution here http://stackoverflow.com/questions/4429068/getting-an-unitialized-constant-error-with-rspec-have-no-idea-whats-causing-it says to require 'rails/all'. Try your luck with that. – shankardevy Jun 19 '14 at 16:32
@huicheese did you ever figure this out? I am having the same error. – Thalatta Jul 21 '14 at 22:16

@Thalatta Hi i eventually just placed require 'spec_helper' at the top and nothing else. try it :) – Hanzawa Naoki Jul 22 '14 at 02:17
