popwin post-:config hook: symbol's value as variable is void: purpose-mode

[vv111y]

Description

serious crash. Can't get spacemacs to boot.

Reproduction guide 🪲

• Start Emacs
• try install kitchin/ox-ipython
• find out babel has some bug, dig around,
• run :spacemacs/recompile-elpa as per Org-Mode Evaluation of code disabled #7641
• other problems. keep deleting elpa, updating packages, updating .emacs.d
• remove .emacs.d entirely, remove any new .spacemacs config
• re-install spacemacs from scratch, below problem still shows up.
• exclude window-purpose. no change

Observed behaviour: 👀 💔
get's stuck here, even after re-install spacemacs from scratch

Warning (initialization): An error occurred while loading ‘/Users/Will/.emacs.d/init.el’:

File error: Cannot open load file, No such file or directory, window-purpose

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.

Expected behaviour: ❤️ 😄
actually startup

update:
I rolled back packages to when I updated on sept 16, and also .emacs.d to commit 9341e1d on develop branch and now it's working.

And also running emacs V25.2.1, instead of V25.3

[bmag]

The backtrace and the observed behavior show two different errors. Is this the same as #9642, or is it another error? Also, can you also answer the question that I asked in #9642 (comment)?

[vv111y]

It is the same problem, and such a simple solution.
For your comment:

1. yes window-purpose-* folder is there as is a non-empty window-purpose.el file
2. I've never done a bisection, I suppose this is a learning moment. Did you still want me to do it?
3. no configs specific to popwin

If nothing else I'll close, thanks @bmag .

Thanks, no need for a git bisect anymore. I'm closing as duplicate.
