macOS "universal" wheel does not contain the Apple Silicon binary

[pietrodn]

When I try to install and run slipcover on a M1 Pro Mac, this is what I get:

$ python3 -m venv venv
$ venv/bin/pip install slipcover
Collecting slipcover

$ venv/bin/python -m slipcover

Apparently the slipcover-0.1.4-cp310-cp310-macosx_10_15_universal2.whl wheel is mislabeled and contains only x86 code.

Thank you, @pietrodn. I'll follow up shortly with a build for you to try out.

@pietrodn, please try from pip install -i https://test.pypi.org/simple/ slipcover==0.1.4.dev202205051057 and reopen the issue if it didn't resolve it. Thank you!

It seems to be fixed, thanks for the quick response! 😄
