Description Greg V 2019-11-28 22:39:10 UTC
Currently, the backports packages are built only on 2.7, and e.g. py-internetarchive only depends on backports.csv on 2.7.

This is wrong:

Traceback (most recent call last):
  File "/usr/local/bin/ia", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 3241, in <module>

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'backports.csv' distribution was not found and is required by internetarchive


These backports packages actually have checks for PY3 inside them, they are not conditional dependencies.

Thank you for the report Greg

Per backports.csv trove classifiers:

Python :: 2
Python :: 2.6
Python :: 2.7
Python :: 3
Python :: 3.3
Python :: 3.4
Python :: 3.5
Python :: 3.6
Python :: 3.7 

These backports are not *just* for 2.7

@Greg Could you provide:

(1) A list of backports that have their python <version-specs> incorrectly limited to 2.7
(2) Confirm that for each of (1), that they are appropriate for, and support Python 3.x
(3) If any of the results of (2) show that they are not appropriate for specific 3.x versions (such as an upper version limit), please note those explicitly too

Thanks!

^Triage: As this involves multiple python ports, and python ports and framework compliance with regard to correct version specifications, assign this to python@ keeping original maintainer (of backports.csv) CC'd
