emacs组织模式导出odt文件，但使用PDF查看器打开

出于某种原因，组织模式正确地导出到ODT文件，但使用默认的PDF查看器（okular）而不是libreoffice打开它。我尝试过类似案例中提到的所有解决方案，但没有任何运气。为了便于参考，我在下面复制了init文件的相关部分。我的emacs是27.0.50，我的组织模式是9.1.13

;; Enable export in ODT format
(eval-after-load "org" '(require 'ox-odt nil t)) ; enable odt backend
;; Open ODT files with libre office
(defun my-org-export-to-odt-and-open ()
  (interactive)
  (org-open-file (org-odt-export-to-odt)))

在我的自定义变量集中

 '(org-file-apps
   '((auto-mode . emacs)
     ("\\.mm\\'" . default)
     ("\\.x?html?\\'" . default)
     ("\\.odt\\'" . "libreoffice %s") 
     ("\\.pdf\\'" . "okular %s")))

提前感谢您的帮助

这是组织文件应用程序的输出值

Value:
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.odt\\'" . "libreoffice %s")
 ("\\.pdf\\'" . "okular %s"))
Original value was 
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

这是我试图导出NOTES.org文件时，edebug在

org open file

上的一个输出

事实上，我一直在前进，在org文件应用程序中没有任何选项可以与之匹敌。

经过大量挖掘，我发现了以下帖子： 由此产生了以下解决方案：

;; Enable export in ODT format
(setcdr (assq 'system org-file-apps-defaults-gnu ) "xdg-open %s")
(setq process-connection-type nil)

没有在组织文件应用程序上配置任何内容。

首先确保您正在运行的emacs中设置了

org file apps

：C-h v org file apps RET说什么？如果不包括odt设置，则不使用自定义文件。如果它确实包含odt设置，我将在

org open file

上使用它来查看出错的地方。@NickD很抱歉回复得太晚，感谢您的帮助。我将把

组织文件apps

和

组织打开文件

的输出放在上面。由于我不是一个非常有经验的lisp用户，我可能需要一些帮助来解释它。

;; Enable export in ODT format
(setcdr (assq 'system org-file-apps-defaults-gnu ) "xdg-open %s")
(setq process-connection-type nil)
