Hi,

Trying to install slipcover with pip 22.3.1 and Python 3.11.0 gives an error with the following output:

╰─> slipcover

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Looks to be an issue with the slipcover.tracker extension? I’m on macOS Big Sur 11.7.1 if that makes any difference. Let me know if I can provide any further information.
