Install with setup.py bug

[vsoch]

Describe the bug
I'm creating a package for spack, and we cannot install with the traditional setup.py build because package metadata is missing in te setup.py. I am wondering if it would be possible to add?

To Reproduce
Steps to reproduce the behavior:

1. Download .tar.gz from pypi
2. build

# This is run from spack, python 3.8.12
python -s setup.py --no-user-cfg' build

4 errors found in build log:

Error in terminal

see above! I pre-emptively pasted 😆

Expected behavior
Normally setup.py build should be successful.

Environment you are running Tern on

Ubuntu 20.04, no containers!
Python 3.8.12

Thank you!

Hi @vsoch - thanks for the issue. We use the setup.cfg file to house our package metadata. Are you able to pull the info from there?

[vsoch]

@rnjudge based on the error message, I do think the install is using setup.cfg (sorry for not realizing this) and the issue is that the fields are deprecated. E.g., here is the long-description:

tern/setup.cfg

Line 12 in 38d5c76

long-description = file: README.md

which should be renamed to long_description.

[vsoch]

I can open a quick PR to test updating these metadata fields.

Suggested change! #1085

Thank you for this help! Tern is now added to spack, so people can try out install via there, or if interested in Docker/Singularity containers there is a containerize command to do the same and generate in a dockerfile, or modules too. spack/spack#27599 (comment)
