在Emacs中运行Ubuntu 16.x时，出现以下错误消息。
Warning (initialization): An error occurred while loading `/home/shree/.emacs':
File error: Cannot open load file, no such file or directory, org-journal
我的.emacs文件是：
(setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/")
("marmalade" . "http://marmalade-repo.org/packages/")
("melpa" . "http://melpa.org/packages/")))
(setq org-journal-dir "/home/shree/git-shree/journal")
(require 'org-journal)
我已经升级到emacs 27.x，但是即使重启后仍然显示emacs 24.x。
