Cannot popup autocomplete prompts in python-mode about auto-complete HOT 11 CLOSED

Please check the following:

1. Is AC mode is enabled ?
2. Is ac-auto-start non-nil ?
3. M-: (auto-complete '(ac-source-ropemacs))

from auto-complete.

Thanks for your update :)
Answers:

1. AC mode is ON
2. ac-auto-start is 2
3. nil

My configurations is below.
;; Auto Complete
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/site-lisp/auto-complete/dict")

Can you get completions by M-: (rope-completions) at the position ?

from auto-complete.

Yes. I can get them. And M-/ runs the command rope-code-assist if AC mode is enabled.

from auto-complete.

Please try again after evaluating the following code:

(setq ac-source-ropemacs
'((init
. (lambda ()
(setq ac-ropemacs-completions-cache
(mapcar
(lambda (completion)
(concat ac-prefix completion))
(rope-completions)))))
(candidates . ac-ropemacs-completions-cache)))

from auto-complete.

You may get errors or ac-ropemacs-completions-cache is forever nil.

from auto-complete.

Yes, ac-ropemacs-completions-cache is always nil, so still not work. What should I do?

from auto-complete.

Hmm... I have to look into more deeply. Sorry for inconvenience.

from auto-complete.

Okay, Thanks for your great work! I like AC. Please let me know if you need help.

from auto-complete.

I use the configuration on http://www.enigmacurry.com/2009/01/21/autocompleteel-python-code-completion-in-emacs/, but cannot work well yet. Please refer to the latest comment.

(add-hook 'python-mode-hook
(lambda ()
(auto-complete-mode 1)
(set (make-local-variable 'ac-sources)
(append ac-sources '(ac-source-rope)))
; (append ac-sources '(ac-source-rope) '(ac-source-yasnippet)))
(set (make-local-variable 'ac-find-function) 'ac-python-find)
(set (make-local-variable 'ac-candidate-function) 'ac-python-candidate)
(set (make-local-variable 'ac-auto-start) nil)))

(set (make-local-variable 'ac-sources) (append ac-sources '(ac-source-yasnippet)))
(setq ac-auto-start nil)
(ac-set-trigger-key "TAB")

from auto-complete.

I found the ultimate solution. Hope it works for you.

(ac-ropemacs-initialize)

(defvar dss-ropemacs-completions-cache nil)
(defun dss/rope-candidates (prefix)

(setq dss-ropemacs-completions-cache

(ac-define-source dss-rope

(cache . t)

(ac-define-source dss-rope-dot
