updating package helps partially it fails on different tests, but tox -e py38-pip1923 runs fine so I 'll probably need to update some dependency. And check in copr if doesn't break pipenv that will take a while.

I think that test_resolve should be skipped.

got it working https://copr.fedorainfracloud.org/coprs/pkopkan/python-vistir/build/1129958/ but pipenv fails to build https://copr-be.cloud.fedoraproject.org/results/pkopkan/python-vistir/fedora-rawhide-x86_64/01129965-pipenv/build.log.gz

between versions of pip-shims function 'do_import' got removed and I didn't find any function similar to it.

Could you try to fix the package without updating it?

I can think of either skipping tests or test the library against the bundled pipenv pip.

This now blocks the Python 3.9 rebuild.

Patrik, can you do this in any reasonable time? Or should someone else take this?

If reasonable timeframe is two weeks then probably no.

Upstream will adapt api of newer pip-shim's version. So the most effective/lazy sollution is to skip broken tests until that happen.
