I just grabbed the latest Mac version and started setup.

It failed with:

```auto
error: unexpected argument '--end-1734104644037:0 found

   tip: to pass '--end-1734104644037:0' as a value use '-- --end-1734104644037:0'

Usage: uv pip install --upgrade […]

```

I’m happy to do this manually from the Terminal, but I’m not sure where to find the initial setup scripts?

Same issue. Here is what showed before the error:
