error "Need package ‘org-20150330’, but only 9.1.9 is available"

[tamouse]

Started getting this today after resetting my .emacs.d directory...

[doolio]

What version of org do you use and from where (built-in, from org elpa, org-plus-contrib from org elpa?

[tamouse]

I believe it's built-in. I'm not doing anything to load it.

My current config is here: https://github.com/tamouse/my-emacs-d

[doolio]

And are you still using Emacs 24? The README suggests that the org shipped with Emacs may be out of date for org-reveal and is likely the case if you are still using Emacs 24. However, Org v9.1.9 is the latest version. org-reveal's dependency for org-20150330 is to ensure that you have a minimum compatible version. If you have v9.1.9 installed then it should work.

In terms of your config,

(setq org-reveal-root "https://cdn.jsdelivr.net/reveal.js/3.0.0/")
(setq org-reveal-mathjax t)

You may want to update to the latest reveal.js available at https://cdn.jsdelivr.net/npm/reveal.js@3.6.0 and the second variable is now obsolete (but still available). By default it too uses a CDN for MathJax. See org-reveal-mathjax-url.

[tamouse]

emacs-version reports 25.1.1

[tamouse]

I think I see the problem, although I'm not sure. org-version is 8.3.10, which is clearly not new enough. I don't know why it's giving the error about 9.1.9, though.

[tamouse]

i've install 9.1.9 from elpa, but i'm still getting the original error when it gets to (use-package ox-revel ...) it still fails with the message above

Looking at package-list-packages, it says ox-reveal is incomaptible:

ox-reveal          20161027.226  incompat   melpa      reveal.js Presentation Back-End for Org Export Engine

[doolio]

In your elpa directory do you have more than one version of org? You likely have the v9.1.9 you installed and the one installed by org-reveal when you installed it namely org-20150330. I had to remove the org-20150330 directory installed by org-reveal as it was unnecessary having already installed the latest org with org-plus-contrib from elpa. This is a known issue with installing packages from (M)ELPA that already ship with Emacs. See this use-package discussion.

Here's my elpa/ directory:

Only one org directory.

[tamouse]

This is what is now working:

1. use the formula to load org from this comment: No way to install org jwiegley/use-package#319 (comment)
2. git clone this repo, and copy ox-reveal.el to a location on the load-path

It's not what I hoped for, but it works, and I'm good with it. Thanks for your help, I was getting worried since I have a class coming up and didn't want to have to redo all the slides. :)

[doolio]

OK, good. Glad to hear it. If you produce many slides you may be interested in this project I've recently discovered. It uses a fork of org-reveal. There is also a howto which I'm following to produce all my future slides and keep them under version control and in the same place.

[bsima]

This fix worked for me too.

(use-package ox-reveal
  :load-path "~/src/org-reveal") ;; or wherever you cloned this repo

[cesquivias]

I don't think this issue should be closed. Although you can download the source, not resolving this problem effectively breaks the melpa package. Can we just update the org dependency version?

[WeeBull]

Getting help on the package shows that it's dependencies are unable to be met.

ox-reveal is an incompatible package.

     Status: Incompatible because it depends on uninstallable packages.
