Inconsistent version: filename has '2.2.0', but metadata has '0.0.0'

[svenfoo]

Getting these errors when attempting to build a Docker container that has nats-py==2.2.0 in the requirements.txt:

WARNING: Requested nats-py==2.2.0 from https://files.pythonhosted.org/packages/21/00/831ef555466bcde9419fc953ded17cb83e255733b248bf0e72a0a11759b6/nats-py-2.2.0.tar.gz (from -r /opt/tmp/requirements.txt (line 5)), but installing version 0.0.0

I do not get any errors if I use nats-py==2.1.7 instead. But I would actually like to use the new API. Maybe something went wrong when the 2.2.0 package was built? The Meta section on https://pypi.org/project/nats-py/ also does not look right to me.

I do not understand why this happens on Ubuntu 22.04 (or actually in a Docker container based on Ubuntu 22.04). All I can say is that other packages (and other versions of nats-py) do not seem affected. So maybe this is not a bug in nats-py after all, but I'm puzzled and have no idea how to proceed.

Hi @svenfoo, thanks for the report. We attempted to adopt a new way to build the package here (https://github.com/nats-io/nats.py/pull/341) and looks like there are some problems then... Thanks for sharing how to reproduce, I will take a look soon.

[wallyqs]

@svenfoo could you share a simple version of the Docker file that you are using to build this? Interested in the docker FROM image for the ubuntu layer to try to reproduce, thanks in advance!

[svenfoo]

Here's the most simple Dockerfile I could come up with that reproduces the problem:

FROM ubuntu:22.04

RUN apt-get update && apt-get install -y python3-pip

# The next line would update pip. Tried with and without it, doesn't seem to make a difference.
# RUN python3 -m pip install -U pip

RUN pip install nats-py==2.2.0

[svenfoo]

This, on the other hand, works. So it seems to be something with the Ubuntu image.

FROM python:3.10.6

RUN pip install nats-py==2.2.0

[svenfoo]

Adding the option --use-deprecated=legacy-resolver to the pip install command allows me to install nats-py 2.2.0 in the Ubuntu based container, albeit with the wrong version:

Successfully installed nats-py-0.0.0
