I have a problem with "WARNING: CIDER's version (0.14.0) does not match cider-nrepl's version (nil). Things will break!”. I tried sending (nrepl-send-sync-request '("op" "describe") (current-buffer)) and it doesn’t return aux dictionary. I have leiningen 2.7.1 and I use cider-stable. I’ve tried 0.15.0-SNAPSHOT version but it doesn’t work as well. What can be wrong? I’ve tried with deleting .emacs.d/elpa.
