Latest pip release fails

[kerimoyle]

Details

• Read the Docs project URL: https://readthedocs.org/projects/libcellml-tutorials
• Build URL (if applicable): https://readthedocs.org/projects/libcellml-tutorials/builds/10297974/ but the error was first encountered here: https://readthedocs.org/projects/libcellml-tutorials/builds/10297436/ when pip was updated

Expected Result

Build without failing ... :)

Actual Result

Currently all builds are failing because the automatic upgrade (since #4823 ) to pip 20.0 was buggy (see pypa/pip#7620 ). There's now a 20.0.1 release which seems to have fixed the problem for others ... but how can I force my readthedocs to also upgrade to the .1 version?

[stsewd]

Hi, you can force a clean installation by wiping the environment https://docs.readthedocs.io/en/stable/guides/wipe-environment.html

That will download the latest pip instead of using one from cache

[kerimoyle]

Brilliant - thanks so much for the quick reply :)

Hi,
Wiping master or latest only fixes this for me for a single build, the next one fails with the same error.
All builds are triggered via the v3 api.

ImportError: cannot import name 'PackageFinder' from 'pip._internal.index' (/home/docs/checkouts/readthedocs.org/user_builds/o-ran-sc-doc/envs/master/lib/python3.7/site-packages/pip/_internal/index/__init__.py)

@Aricg that's weird. Did you wipe only once? I can think of a reason where the wipe didn't propagate to all servers.

[Aricg]

@stsewd I have done it multiple times to both stable and master to try to make it "take"
in each case, it only "takes" once.

[stsewd]

@Aricg can you please trigger a wipe for latest but don't trigger any build. I want to check the servers for something

[stsewd]

@Aricg I just did it by myself from the admin. I think I found the problem #6571

[peterjc]

Like @Aricg in the last day or so I have tried wipe only for the problem to recur:
https://readthedocs.org/projects/thapbi-pict/builds/

It looks like the fix for #6571 was merged about 25 minutes ago, so hopefully the fix will go live shortly.

[stsewd]

@peterjc probably it will be live next week

[peterjc]

Thanks - I'll do a manual wipe as needed until then.

[johannfaouzi]

Is it possible to do a manual wipe for pull requests? I can't find a way to do so.

[humitos]

@johannfaouzi currently, no. We don't support that yet.

[SchoolGuy]

This is breaking this PR cobbler/cobbler#2254

The build environment cannot be wiped because this is (at least to my knowledge) not possible on PR's.

@SchoolGuy see #6566
