(void-function ivy-set-display-transformer)

[manuel-uberti]

Hi,

I've just upgraded counsel from MELPA. When using counsel-M-x this is what I get:

Debugger entered--Lisp error: (void-function ivy-set-display-transformer)
  ivy-set-display-transformer(counsel-M-x counsel-M-x-transformer)
  byte-code("\300\301\302\"\210\303\301\304\"\207" [ivy-set-actions counsel-M-x (("d" counsel--find-symbol "definition")) ivy-set-display-transformer counsel-M-x-transformer] 3)
  autoload-do-load((autoload "counsel" "Ivy version of `execute-extended-command'.\nOptional INITIAL-INPUT is the initial input in the minibuffer.\n\n(fn &optional INITIAL-INPUT)" t nil) counsel-M-x)
  command-execute(counsel-M-x)

If you need me to help with more informations to debug the problem, please feel free to ask.
Could it be related to this piece of code in counsel.el?

;;** `counsel-M-x'
(ivy-set-actions
 'counsel-M-x

I'm starting to think it's an issue with package.el. Since counsel.el clearly depends on ivy.el, which was also updated. However, for some reason while counsel.el was reloaded, ivy.el wasn't reloaded previously.

An Emacs restart always fixes this issue though.

Or if you don't want to restart, locate the package and reload the new ivy.el, then the new counsel.el.

But really, this should be the package manager's job.

I restarted Emacs, but I still got the error.

Just ran into this as well when updating.

I think MELPA built and is serving the latest counsel (dated today) but not the latest swiper package (dated yesterday). It looks like it is still building, so it may resolve itself within a couple hours.

I see. I pushed the updates to both ivy.el and counsel.el at once. Then it's MELPA's fault for serving update in the dependent package without first checking if any dependencies need to be updated. Anyway the problem will be solved when the build is finished, so it's not a big deal.

I can confirm everything works now that swiper is up to date on MELPA.
