[英]Why is evaluation of this python code block disabled in emacs org mode?
In a python source block in org-mode, after hitting Cc Cc, emacs says emacs说,在org-mode中的python源块中,在点击Cc Cc之后
Evaluation of python source block is disabled
禁用对python源块的评估
Could anyone explain why? 谁有人解释为什么?
Simon's answer is not right if the org-mode version is >= 9. Here is another question on the same problem. 如果组织模式版本为> = 9。这里是另一个西蒙的答案是不正确的问题,同样的问题。
The solution 解决方案
cd .emacs.d
cd elpa
cd org-xxxx
rm *.elc
Then, it's better to byte-recompile the directory of the org-xxxx. 然后,最好对字节重新编译org-xxxx的目录。 To do that, start emacs, then
为此,请启动emacs
C-0 M-x byte-recompile-directory RET ~/emacs.d/elpa/org-xxxx
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 . 为了评估特定语言的组织模式的代码块,你将不得不定制
org-babel-load-languages
描述在这里 。 Evaluating the following will probably resolve your issue: 评估以下内容可能会解决您的问题:
(org-babel-do-load-languages
'org-babel-load-languages
'((python . t)))
From the docs: 来自文档:
org-babel-load-languages
is a variable defined inorg.el
.org-babel-load-languages
是org.el
定义的变量。 Original value was((emacs-lisp . t))
原值为
((emacs-lisp . t))
Languages which can be evaluated in Org-mode buffers.
可以在组织模式缓冲区中评估的语言。 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.
此列表可用于加载对以下任何语言的支持,请注意每种语言将取决于一组不同的系统可执行文件和/或Emacs模式。 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.当一个语言被“加载”时,那个语言的代码块可以用
org-babel-execute-src-block
进行评估,默认绑定到Cc Cc
(注意org-babel-no-eval-on-ctrl-c-ctrl-c
变量可以设置为从Cc Cc
键绑定中删除代码块评估。默认情况下,只加载Emacs Lisp(没有要求)。You can customize this variable.
您可以自定义此变量。
This variable was introduced, or its default value was changed, in version 24.1 of Emacs.
在Emacs的版本24.1中引入了此变量,或者更改了其默认值。
