I get the following message when starting Emacs:

Warning (emacs): Unable to activate package `elpy'.
Required package `highlight-indentation-0.5.0' is unavailable
Warning (emacs): Unable to activate package `elpy'.
Required package `highlight-indentation-0.5.0' is unavailable
Warning (emacs): Unable to activate package `elpy'.
Required package `highlight-indentation-0.5.0' is unavailable

I then found this Q&A: Find elisp origin of warning

So I followed the accepted answer and added the following to the top of my .emacs file:

(setq debug-on-message "Unable to activate package `elpy'.")

and then restarted Emacs, but nothing happened. Was I supposed to fall into the debugger?

How can I find what specific line in my .emacs file trigger the warning?

    This is happening during package activation, so it's not your init file's fault. Just install the missing package. – Malabarba Jan 11 '15 at 23:26
  • Thanks @Malarba. I have uninstalled these packages precisely because they are [giving me problems](https://github.com/jorgenschaefer/elpy/issues/435), so what I want to do is find out what is loading them. – Amelio Vazquez-Reina Jan 12 '15 at 02:20
  • Elpy is loading it. As explained in the warning and in the (elpy) issue you linked. ;-) – Malabarba Jan 12 '15 at 02:55

This is happening during package activation, so it's not your init file's fault.

What's happening

The warning is telling you everything you need to know. elpy needs to load highlight-indentation, but the package's not installed.

What to do

Either

  • install the missing package
  • or delete elpy.

  • Is it possible to check if the specific package failed to be activated then install it automatically so I don't need to install it manually? – CodyChan May 04 '18 at 07:53
