[JelleZijlstra]

I guess the problem here is that we don't provide a wheel, and while building the sdist we require setuptools. I'm actually not sure why there are no wheels for the most recent two releases; perhaps @cooperlees knows?

[ichard26]

For context, the reason why building from the sdist is a pain is that the build isolation pip enforces by default (see PEP 517) means installing a fresh setuptools and wheel into such isolated build environment. Now your locally curated wheelhouse doesn't have a copy of setuptools or wheel so the isolated build environment creation failed.

A bypass is passing --no-build-isolation to pip.

@JelleZijlstra for 20.8b1, the wheel had outdated files in it due to being built in a dirty environment, so it was deleted. Maybe same story for 20.8b0?

[ichard26]

Maybe same story for 20.8b0?

Doing some digging, yes, same story for 20.8b0.

Thanks for the prompt replies!
I can confirm that the problem does NOT persist with black-19.10b0-py36-none-any.whl

[JelleZijlstra]

We do have wheels for the last few releases, so this should no longer be a problem.
