Org Babel Source Block Native Fontification

Question

我正在尝试使用org-babel源块来执行本机语法突出显示。我已将org-src-fontify-natively设置为true，但仍然没有看到任何内容。

这是我的相关配置：

(setq org-babel-default-header-args
  '((:session  . "none")
    (:results  . "replace")
    (:exports  . "code")
    (:cache    . "no")
    (:noweb    . "yes")
    (:hlines   . "yes")
    (:tangle   . "yes")
    (:padnewline . "yes")))

(org-babel-do-load-languages
 'org-babel-load-languages
 '((emacs-lisp . t)
   (R          . t)
   (js         . t)
   (clojure    . t)
   (org        . t)
   (sh         . t)
   (python     . t)
   (dot        . t)
   (prolog     . t)
   (lisp       . t)
   ))

(setq org-edit-src-content-indentation 0   
      org-src-tab-acts-natively   t        
      org-src-fontify-natively    t        
      org-confirm-babel-evaluate  nil      
      org-src-window-setup 'current-window 
      org-src-preserve-indentation t
      org-src-strip-leading-and-trailing-blank-lines t
      )

这是org-babel-view-src-block-info（C-c C-v I）：

Lang: emacs-lisp
Properties:
    :header-args    nil
    :header-args:emacs-lisp     nil
Header Arguments:
    :cache      no
    :exports    code
    :hlines     yes
    :lexical    no
    :noweb      yes
    :padnewline yes
    :results    none
    :session    none
    :tangle     yes
