UV ignores PIP_INDEX_URL?

[david-waterworth]

We use AWS code-artifact as a private PyPi repository. Different tools (poetry/pip etc) have different mechanisms for controlling where to install from, i.e. for pip you need to set

PIP_INDEX_URL="https://aws:${CODEARTIFACT_AUTH_TOKEN}@${domain}-${account}.d.codeartifact.${region}.amazonaws.com/pypi/${repository}/simple/"

I did a quick test of uv - I like what I see so far but first without --verbose it doesn't tell me the index url where packages are being installed from. I think this is useful in cases where users are using a private index.

Setting --verbose it seems that it's ignoring PIP_INDEX_URL, i.e. uv pip install torch --verbose

It looks like its downloading from https://files.pythonhosted.org and not AWS. Is there an alternative mechanism for setting PIP_INDEX_URL globally?

Also in passing, the default timeout of 300s isn't long enough to install torch.

Hi! You can use UV_INDEX_URL instead.
