This seems to stem from the update of 'python-black' in

I’d rather not revert but add an older variant of python-black for elpy.

Perhaps the issue would vanish if we move to Elpy 1.32? I had started

In any case I'm sure sirgazil is not the only user of this package, so

we should try and find a resolution quickly.

As a side note, this bug report could have been easily prevented by

building the few packages listed by 'guix refresh -l python{,2}-black'

before pushing! Not to single out Ricardo here (I forget this too

occasionally), but I expect contributors to do this in general and think

we should keep a low threshold for reverting breaking commits.

Hello,

Fixed with commit 4ef89d884db8dae3aa300e36a3ad89def374e012.

With the changes I've made to Emacs, Elpy can now be tested in a

container easily with:

Enjoy!

Closing.
