Emacs + Rope + Python produces lisp error

I'm trying to use Ropemacs with AutoComplete in Emacs but I keep getting a Debugger error:

Debugger entered--Lisp error: (void-function rope-completions)
  (rope-completions)
  eval((rope-completions))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)

The symbol rope-completions has no documentation from C-h S. It only appears once, in the auto-complete-config. I've downloaded the latest ropemacs, ropemode, pymacs, python-rope and probably borked any apt system consistency I had.

When I remove this function from the config files auto-complete turns the cursor red when it tries to complete. I can't find reference to this function anywhere on my system.

Auto-complete is working perfectly for me in Lisp. How can I get auto-complete and Rope to work together to give me auto-completion for Python in Emacs?

EDIT: I cannot see the definition of rope-completions through C-h f. Here is the output of my Pymacs buffer:

Solution

  • The only way I was able to do it in the end was to ignore all other tutorials and just use the Emacs For Python Github. It works really well, combines a lot of packages that I was looking to use anyway and is easy enough to configure so that it doesn't mess up my existing bindings and settings.
