BUG? No interpreter found in search path

[turbotimon]

Problem

It is unclear to me, why uv venv does not find Python 3.12 in the system path. Discover of Python version claims its will look in PATH. And uv python find does find it.

$ uv venv
  × No interpreter found in search path

But it should work..

Here is what other commands find:

$ python --version
Python 3.12.7

$ which python
/etc/profiles/per-user/erti/bin/python
# context: it's a symlink to /nix/store/542jax1lz8sfq1gqk2wrdskr334sswnx-python3-3.12.7-env/bin/python3.12

$ echo $PATH
...:/etc/profiles/per-user/erti/bin:...

$ uv python find
/nix/store/542jax1lz8sfq1gqk2wrdskr334sswnx-python3-3.12.7-env/bin/python3.12

(yes, i'm using nixOS)

Context

My config is

$ cat ~/.config/uv/uv.toml
python-preference = "only-system"
python-downloads = "manual"

uv version is: 0.5.18

Workaround

This works however

uv venv --python $(which python)

Can you include the logs with --verbose?
