After installing fromager to a virtualenv and invoking it via Python launcher, it fails with "No such file or directory: pypi-mirror". It seems that fromager expects pypi-mirror to be on the executable search path:
fromager 🐚 py -3.12 -m venv .venv
fromager 🐚 py -m pip install -q fromager
fromager 🐚 py -m fromager bootstrap requests
bootstrapping 'cpu' variant of [('toplevel', 'requests')]
[Errno 2] No such file or directory: 'pypi-mirror'

Activating the virtualenv works around the issue.
It would be more reliable if the mirror were invoked as {sys.executable} -m pypi_mirror.
