`viur update requirements` fails in a non-pip-environment

[phorward]

I'm trying uv as a replacement for pipenv. It works nice so far, but uv run viur update requirements fails, and it also seems that this command heavily relies of a pipenv-based environment.

$ uv run viur update requirements

Ok now even when pip is added as a dev-dependency, but no Pipfile is available, the process also fails:

$ uv run viur update requirements
