This broke my install too

Slightly off topic, but how would I install @IsaGrue's commit into my environment until this package is updated?

@Burn1n9m4n please see comment from @leifdenby on this earlier issue. Looks like you could run a similar command to the following to install @IsaGrue's fork with one extra commit.

python -m pip install git+https://github.com/leifdenby/nb_black/#egg=nb_black

However, this workaround will not be suitable for everyone. Please can we get a proper fix for this soon? It's stopping people installing what is otherwise a very useful package.

Sharing the link to the Pull Request I opened to fix this. Hopefully it get's reviewed and merged soon.

Still affected by this. does anyone know if there's a workaround? downgrading to a previous well known version?

@efab2022 downgrading to 1.0.5 seems to fix this issue during my install
