  I'm getting the same error in a fresh rails application using rails-edge. In this case I'm not declared anything, I created it and I ran script/generate (with any argument, all return the same), an then...

  
  rails/actionpack/lib/action_controller/session/cookie_store.rb:163:in `ensure_session_key': A key is required to write a cookie containing the session data. Use config.action_controller.session = { :key => "_myapp_session", :secret => "some secret phrase" } in config/environment.rb (ArgumentError)
  	from /Users/marcosariaspena/code/tests/test/vendor/rails/actionpack/lib/action_controller/session/cookie_store.rb:74:in `initialize'
  	from /Users/marcosariaspena/code/tests/test/vendor/rails/actionpack/lib/action_controller/middleware_stack.rb:72:in `new'
  

  The environment apparently ignores session = {} declaration, both in initializer/session_store.rb or in environment.rb.

  Some rake tasks returns this error too (such as "rake middleware")

  I've found something about this error:

  This commit changes the way SessionStore is initialized, allowing custom settings in session store...

  Well, the actual code is:

  
  # actionpack/lib/action_controller/middlewares.rb - line 7
  use lambda { ActionController::Base.session_store },
    ActionController::Base.session_options
  

  This, for some reason, it's not interpreted as expected and doesn't load ActionController::Base.sesion_store, whatever value it has, you must add :if => true at the end to force that load

  
  # actionpack/lib/action_controller/middlewares.rb - line 7
  use lambda { ActionController::Base.session_store },
    ActionController::Base.session_options, :if => true
  

  I'm trying to figure out in my local rails clone why is this happening

  I've found another strange thing regarding this error

  If you change this code

  
  # actionpack/lib/action_controller/middleware_stack.rb - line 17
  options = args.extract_options!
  if options.has_key?(:if)
    @conditional = options.delete(:if)
  else
    @conditional = true
  end
  args << options unless options.empty?
  

  For this one, which is practically the same (I'm going to annotate the differences), all works fine

  
  # options = args.extract_options! always do a pop in args
  if args.last.is_a?(Hash) && args.last.has_key?(:if)
    @conditional = args.last.delete(:if)
    # only do a pop if the args.last remains empty after deleting the :if option
    args.pop if args.last.empty?
  else
    @conditional = true
  end
  # args << options unless options.empty? should retrieve the extracted options without the if, but this don't work, only if the pop is made when the args.last is an empty hash
  

  As you can see, this 2 pieces of code are practically the same, but produces 2 different results. I think the eval() of actionpack/lib/action_controller/middlewares.rb file might be related with this behavior.

  I don't think the whole ticket it's a duplicate, the error pointed by Akira Matsuda its still there.

  I've updated my rails repo with the middleware fix by Sven Fuchs, and a fresh app works fine, but once you specify a config.gem which you have not installed yet, the error raise again

  
  Rails::Initializer.run do |config|
    config.gem "aws-s3", :lib => "aws/s3" # Or any gem you had't installed yet
    # ..
  end
  

  "rake gems" fails with this message:

  
  rake aborted!
  A key is required to write a cookie containing the session data. Use config.action_controller.session = { :key => "_myapp_session", :secret => "some secret phrase" } in config/environment.rb
