Bug: ModuleNotFoundError: No module named 'jsonschema.compat'

[peterdudfield]

I'm currently getting the error - ModuleNotFoundError: No module named 'jsonschema.compat'
I think this first started today

I get this on python 3.9.7, when running import neptune

This could be an error with 'swagger_spec_validator'

See error here

For reference I have also created a big report here: Yelp/swagger_spec_validator#149

Getting the same error too, it started 9hrs ago

import python_jsonschema_objects as jso
/home/builder/.local/lib/python3.6/site-packages/python_jsonschema_objects/init.py:12: in
from jsonschema.compat import iteritems
E ModuleNotFoundError: No module named 'jsonschema.compat'

Seems to be a move away from iteritems, to '.items()' instead

I do not know if this is related or not to python-openapi/openapi-spec-validator#130, another openapi validator that stopped working when upgrading to jsonschema 4.0.0.

I've created a PR that added compact.py back in with a warning

I do not know if this is related or not to p1c2u/openapi-spec-validator#130, another openapi validator that stopped working when upgrading to jsonschema 4.0.0.

This looks a different issue, but also related to the release of 4.0.0

Hi all.

jsonschema.compat was documented both in its docstring as well as in a note in the documentation as being private. It was also never documented to end-users (i.e. other than that note, no list of what's in there appeared anywhere). The reason it existed at all was simply because jsonschema is going on 9 years now and existed before something like six was usable, otherwise jsonschema would have used six and not its own compat module -- but jsonschema.compat definitely was not intended (or promised to be usable) by any other users than jsonschema itself.

So it's unfortunate some downstream packages used things from it anyhow, but it's not covered by the deprecation policy. These packages should remove their use of it and use six or an equivalent if they're still supporting versions where it's needed.
