FYI: nose is no longer maintained. You should look to migrate to nose2, though it's a different paradigm than the original nose.
Where is if isinstance(tests, collections.Callable) and not is_suite: coming from? I don't see it in suite.py.
I believe that's coming from a transformation that's being applied by an old version of 2to3, see e.g. https://docs.python.org/3.4/library/2to3.html#2to3fixer-callable. I guess the python3 wheel for nose on pypi was generated using python3.4 or older. The transformation applied by 2to3 was updated in python3.5.
I suspect that if you tried building a nose wheel from the sdist tarball using a recent python3 version and installed the resulting wheel that would work. Haven't tried it. However pip install nose will be broken forever unless someone does a release since pip will always try to grab the python3 wheel that's on pypi for the last release.
Good find! This works for me on Python 3.9, to prevent installation from wheel:
pip install -U nose --no-binary :all:

The Do not use binary packages workaround doesn't work in windows, nosetests executable can be found, Is there other workaround? C:>nosetests 'nosetests' is not recognized as an internal or external command, operable program or batch file.
You could try downloading nose-1.3.7.tar.gz from https://pypi.org/project/nose/#files and then pip install nose-1.3.7.tar.gz, or try https://pypi.org/project/nose-py3/, but it's definitely time to migrate to pytest.
@hugovk I got the same issue today. I found the answer alone. Just replace
nosetests --with-doctest .\tests\doctests.py --verbose
with
python -m pytest --doctest-modules -v .\folder_that_contain_your_code
Where .\folder_that_contain_your_code is your clone. Not your doctest.py
Best reguards.
Fixed in master, but otherwise:
import collections
try:
collections.Callable
except AttributeError:
import collections.abc
collections.Callable = collections.abc.Callable
On my MacOS + Homebrew the problem was present because I was calling python3 setup.py test instead of python3.9 setup.py test (which works).
You should do this, the problem is that the module collections doesnt have the attribute Callable, to call Callable you should before this line collections.abc.Callable. The important thing is that are three or two lines that you should do this modificaction on the nose.py file so you need to go to this path AppData/Local/Programs/Python/Python311/Lib/site-packages/nose Change the permission of the file to exectuable then change the lines of code 541 and 458 the lines are if isinstance(tests, collections.Callable) or isinstance(tests, unittest.TestSuite): instead to run the program correctly write this line if isinstance(tests, collections.abc.Callable) or isinstance(tests, unittest.TestSuite):
