As the title says, I get this error whenever I, or the function I'll show below, call org-babel-tangle. I'm using a org file to configure emacs, which tangles every time it is saved to my init.el.

The config regarding org-babel:

(with-eval-after-load 'org
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((emacs-lisp . t)
     (python . t))
  (setq org-confirm-babel-evaluate nil)))

;; Templates
(with-eval-after-load 'org
  (require 'org-tempo)
  (add-to-list 'org-structure-template-alist '("sh" . "src shell"))
  (add-to-list 'org-structure-template-alist '("py" . "src python"))
  (add-to-list 'org-structure-template-alist '("el" . "src emacs-lisp")))

;; Automatically tangle when saved
(defun tzne/org-babel-tangle-config ()
  (when (string-equal (buffer-file-name)
                      (expand-file-name "~/dotfiles/home/.config/emacs/README.org"))
    (let ((org-confirm-babel-evaluate nil))
      (org-babel-tangle))))
  (add-hook 'org-mode-hook (lambda () (add-hook 'after-save-hook #'tzne/org-babel-tangle-config)))

I'm getting the error:

    Debugger entered--Lisp error: (wrong-number-of-arguments (2 . 2) 3)
  org-babel-do-load-languages(org-babel-load-languages ((emacs-lisp . t) (python . t)) nil)

  load-file("~/.config/emacs/babel.el")

  command-line()
  normal-top-level()

Note: The error comes from a babel.el file because I changed so many times the babel config I thought it would be safer to put it in a separate file to avoid messing other things up.

Plus, I know almost nothing of elisp, my config is built taking snippets of SystemCrafters and DistroTube.

The error is telling you that org-babel-do-load-languages takes two arguments, and you have passed in three. Yes, it is hard to decode this from the stack trace, since you just have to know what the numbers mean. I have pondered ways to improve the error messages, and concluded that the best way to do it is to implement translations into other languages, but even translating them into English is a huge project and I never got started on it.

A quick glance at your code shows a misplaced ).

  • I found the misplaced ), put it on the right spot and the error persists. I even copy and pasted the snippet I got the code from, still no luck. Important to note it was working for years, and yesterday, when messing around with my config, I started getting the error. Jul 10, 2023 at 1:12
