pytest 8.1.1 (just released) contains a consider_namespace_packages argument for import_path. The changes added in #241 use this argument for pytest >=8.2:

but unfortunately the above argument change was included in a "bugfix" 8.1.1 version. This produces errors like the following:

.tox/py39-parallel-cov/lib/python3.9/site-packages/pytest_doctestplus/plugin.py:268: in collect
    module = import_path(fspath, mode=mode, root=self.config.rootpath)
E   TypeError: import_path() missing 1 required keyword-only argument: 'consider_namespace_packages'

when running pytest 8.1.1 with pytest-doctestplus 1.2.0
