Description:

$ pip show zipp | grep Version
Version: 0.0.0

The version should be 2.0.0. As an indirect result, home-assistant is broken:

$ hass

During handling of the above exception, another exception occurred:

Steps to reproduce:
See above

----------------------------------

The problem is that toml is not installed during build(), and setuptools-scm is not invoked as pyproject.toml is not handled. See https://github.com/jaraco/zipp/commit/29c497286e9f8e835c68b7b4ddb9ff3635a273dc for more details.

I feel that importlib-metadata should be dropped (https://bugs.archlinux.org/task/64719); otherwise it or related packages will bite us more in the future.
