Deprecation Warnings using Python 3.7 beta

[csabella]

• Pip version: 9.0.1
• Python version: 3.7 beta
• Operating system: Ubuntu 16.04

Description:

I created a venv under Python 3.7 and am getting the following:
~/pip/_vendor/pyparsing.py:3226: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
elif isinstance( exprs, collections.Iterable ):

~/pip/pep425tags.py:260: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
import imp

I didn't know if you'd want separate issues for the two warnings.

Thanks for the report! The issue in pyparsing needs to be reported upstream, so I've opened https://sourceforge.net/p/pyparsing/bugs/106/. The other one we'll need to look at.

The deprecation warning on import pip isn't new in Python 3.7. I'm getting it in 3.6.4 too (while trying to turn on warnings-as-errors in CI for another project):

$PYTHONWARNINGS="error::DeprecationWarning" python -c "import pip"

Let's try to get rid of these warnings by the next release.

[pradyunsg]

I couldn't find the time to fix this. :/

Pushing this down the road to the next release since I don't think this'd happen in time for 18.0.

[auvipy]

need help? I am up for help if no one step in

[pradyunsg]

Sure. Go ahead. :)

The issue in pyparsing needs to be reported upstream, so I've opened https://sourceforge.net/p/pyparsing/bugs/106/. The other one we'll need to look at.

PyParsing has moved to GitHub. Here's a PR for it: pyparsing/pyparsing#16.

[hugovk]

pyparsing/pyparsing#16 has been merged upstream and released in pyparsing 2.2.1.

Here's a PR to upgrade pip's vendored pyparsing to 2.2.1: #5796.

[pradyunsg]

Oh, nice. We'll be updating the vendored packages before the release so this'll get fixed in vendoring updates.
