I just installed python-mode using melpa and therefore I must be on the latest version.

My .emacs init file consists only of the following lines :

(autoload 'python-mode "python-mode" "Python Mode." t)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
(add-to-list 'interpreter-mode-alist '("python" . python-mode))

I try to execute a program that runs fine in the terminal, but when I hit C-c C-c, ie. py-execute-buffer, there's the following error:

py-choose-shell-by-path: Wrong number of arguments: #[nil

followed by a trail of gibberish:

Gibberish

The command py-shell will result in the similar error message.

Emacs v24.5 OS X Yosemite 10.10.4

  • Well, when I delete compiled el files it works fine. So maybe it has something to do with the emacs compiler? I honestly have no clue how it works. – Literal Jul 21 '15 at 21:51

When encountering a bug, please report it to the maintainer, as you will be not the only one affected and it should get fixed for all.

In case of python-mode.el:

https://code.launchpad.net/python-mode

This time done: https://bugs.launchpad.net/python-mode/+bug/1476933

After looking into py-choose-shell-by-path: the lexical-let might have caused the error. Please check out current trunk, should be fixed.
