出于某种原因，组织模式可以正确导出到ODT文件，但使用默认的PDF查看器（okular）而不是libreoffice打开它。我尝试了在类似的post中提到的所有解决方案，但没有任何运气。作为参考，我将复制以下init文件的相关部分。我的emacs是27.0.50，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)))
以及我的自定义设置变量中
'(org-file-apps
'((auto-mode . emacs)
("\\.mm\\'" . default)
("\\.x?html?\\'" . default)
("\\.odt\\'" . "libreoffice %s")
("\\.pdf\\'" . "okular %s")))
在此先感谢您的帮助。
这是org-file-apps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edebug在org-open-file上的一个输出，当我尝试导出NOTES.org文件时。

我一直往前走，直到如下所示。看起来文件是否匹配为\\.mm\\？

实际上，我一直在前进，并且与org-file-apps中可用的任何选项都不匹配。
