pip wheel doesn't make a wheel of this package

[vassilevsky]

Hello :)

I'm using Sentry which uses Mock which uses this package.

I used to run pip wheel -r requirements.txt and then pip install --no-index --use-wheel --find-links=WHEEL_DIR -r requirements.txt and it worked fine for older versions. But now that this package emerged as a dependency, it no longer works.

I deleted the --no-index flag and the installation works for now. Would be good to skip the index though.
