Description
I ran into a bug with Ubuntu 24, which has (by default) system-wide Python 3.12.
Coincidently I have our own Python 3.12 installed, which is symlinked from /usr/local/bin/python3.12:
$ ls -al /usr/bin/python3.12
-rwxr-xr-x 1 root root 8019136 Nov 6 13:32 /usr/bin/python3.12
$ ls -al /usr/local/bin/python3.12
lrwxrwxrwx 1 root root 39 Nov 27 14:02 /usr/local/bin/python3.12 -> /opt/starfish/python3.12/bin/python3.12
$ which python3.12
/usr/local/bin/python3.12
Now, if I try to run example.py:
# /// script
# requires-python = ">=3.12"
# dependencies = []
# ///
import sys
def main() -> None:
print(sys.version)
if __name__ == "__main__":
main()uv 0.4.30 works:
uv cache clean && ./0.4.30/uv run example.py

uv 0.5.0 and 0.5.20 (latest as I am writing this) fail with ModuleNotFoundError:

If I remove /usr/local/bin from $PATH, it works:
uv cache clean && PATH=/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin ./0.5.0/uv run example.py
Clearing cache at: /home/gozdal/.cache/uv

Reading inline script metadata from `example.py`
3.12.3 (main, Nov 6 2024, 18:32:19) [GCC 13.2.0]
Similarly if I add /opt/starfish/python3.12/bin to PATH:
uv cache clean && PATH=/opt/starfish/python3.12/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin ./0.5.0/uv run example.py

3.12.5 (main, Nov 14 2024, 04:29:17) [GCC 13.2.0]
So it seems that the problem is /usr/local/bin symlink.
