Hi Gary:
I don't believe Guix has packaged it (yet). From their Github page you can
either use pip to install it:
pip install uv
(
since you're on Guix, I'd probably install it so that its local to just your
account:
pip install --user uv
)
or use their installer:
# On macOS and Linux.
curl -LsSf https://astral.sh/uv/install.sh | sh
My recommendation would be to go with their installer since you can easily
update it after installing it using:
uv self update
uv is under very active development and they are very responsive to bugs and
feature requests, so its a good idea to keep it updated on a regular basis.
As an aside, RealPython interviewed the creator of UV, Charlie Marsh and this
screencast is really good. It talks a lot about the capabilities of uv and how
it accomplishes them. From what I've seen, uv is SO good that pretty much the
entire python ecosystem is moving to it as the default package manager for
python.
Hope this helps!
Mike
