Not working with Org version 9.1?

[tanders]

I just installed the latest version of ox-rst (20170418.758) via the Emacs packages facilities, and added the following to an otherwise empty ~/.emacs (just to make sure).

(require 'ox-rst)

When trying to export from within org-mode using C-c C-e, I get the usual export menu, but no rst option shows up. Also, calling org-rst-export-to-rst directly results only in the following message.

Unknown "nil" back-end: Aborting export

My Emacs (Aquamacs 3.3 GNU Emacs 25.1.1) has only loaded a few other packages incl. org-mode version 9.1 (package 20170911). BTW: I found it confusing that the Readme at https://github.com/masayuko/ox-rst says "Ox-Rst relies on the Org-mode 9.0 export framework", while the actual source of ox-rst.el says "Package-Requires: ((emacs "24.4") (org "8.2.4"))".

For completeness, I tried other additional exporters like ox-pandoc, and those work.

What am I missing?

Thank you!

Best,
Torsten

Update: I removed all other org-related packages and after other trials I finally got it working. Not sure which one the culprit was, though.

Have the same(?) problem. I get the following error:

require: Symbol’s function definition is void: org-define-error

Evaluating (org-version returns Org-mode version 9.1.6 (9.1.6-57-gec8590-elpa @ /redacted/.emacs.d/elpa/org-20180219/)

Running GNU Emacs 25.1.1 on Ubuntu 16.04.

opening a separate issue as I seem to be suffering something different entirely.
