I am getting the following warning message since I have upgraded to GNU Emacs 27 on Mac.

I have been using Emacs for org-mode. It's my understanding that org-bibtex should be a part of GNU Emacs, I don't know why org-bibtex cannot be loaded.

Warning (initialization): An error occurred while loading ‘/Users/euijeong/.emacs’:

File is missing: Cannot open load file, No such file or directory, org-bibtex
  • I have the same issue after fresh installation on Ubuntu Mate 20.04, Emacs 27.1. I have not find any solution yet. Suggestions? Here is the error message: Compiling file /home/peter/.emacs.d/elpa/org-ref-1.1.1/doi-utils.el at Mon Mar 15 20:23:21 2021 Entering directory ‘/home/peter/.emacs.d/elpa/org-ref-1.1.1/’ doi-utils.el:52:1:Error: Cannot open load file: No such file or directory, org-bibtex

In version 9.3 org-bibtex has been renamed ol-bibtex with all the link-related libraries, see this commit in the source code repository.

You have to make the same change in your .emacs, if you want to support different org versions you have to check the value of the variable org-version.

  • How to fix it then? Might be silly to ask but I ran into the issue after upgrading to emacs 27 too.
