Bugzilla Automation <bugzilla at FreeBSD.org> has asked freebsd-python (Nobody)

Bug 255579: devel/py-pip: build fails with DOCS option
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255579



--- Description ---
When DOCS option is on, the build calls 'setup.py build_sphinx'.  This error
occurs when using python3.6:

====================
 .
 .
  File "/tmp/pip-20.3.4/docs/docs_feedback_sphinxext.py", line 3
    from __future__ import annotations
				 ^
SyntaxError: future feature annotations is not defined
====================

20.3.4 has a new docs_feedback_sphinxext.py file which has:

from __future__ import annotations


This fails with python3.6.


Workaround: WITHOUT=DOCS for python3.6


The easy change is probably to change USES=python:3.6+ to 3.7+ (this could be
dependent on whether DOCS is on but that is probably more trouble than it's
worth).
