In a python source block in org-mode, after hitting Cc Cc, emacs says
Evaluation of python source block is disabled
Could anyone explain why?
Simon's answer is not right if the org-mode version is >= 9. Here is another question on the same problem.
The solution
cd .emacs.d
cd elpa
cd org-xxxx
rm *.elc
Then, it's better to byte-recompile the directory of the org-xxxx. To do that, start emacs, then
C-0 M-x byte-recompile-directory RET ~/emacs.d/elpa/org-xxxx
Details at here .
Update 1: EmacsWiki on compile file.
In order to evaluate an org-mode code block of a specific language you will have to customize org-babel-load-languages
as described here . Evaluating the following will probably resolve your issue:
(org-babel-do-load-languages
'org-babel-load-languages
'((python . t)))
From the docs:
org-babel-load-languages
is a variable defined inorg.el
. Original value was((emacs-lisp . t))
Languages which can be evaluated in Org-mode buffers. This list can be used to load support for any of the languages below, note that each language will depend on a different set of system executables and/or Emacs modes. When a language is "loaded", then code blocks in that language can be evaluated with
org-babel-execute-src-block
bound by default toCc Cc
(note theorg-babel-no-eval-on-ctrl-c-ctrl-c
variable can be set to remove code block evaluation from theCc Cc
keybinding. By default only Emacs Lisp (which has no requirements) is loaded.You can customize this variable.
This variable was introduced, or its default value was changed, in version 24.1 of Emacs.
