Change in Python3.10 from collections.Callable to collections.abc.Callable

[CarloCogni]

As of Python 3.10, collections.Callable as been replaced with collections.abs.Callable.

This will make nose crash with an AttributeError.

I'm encountering the same problem here in our CI setup.

@EwoutH, I just changed the code in the installed package (perhaps not elegant, but simple and quick)

Last commit 7 years ago, is this component maintained?

@alonbl The project's website says:

Nose has been in maintenance mode for the past several years and will likely cease without a new person/team to take over maintainership. New projects should consider using Nose2, py.test, or just plain unittest/unittest2.

I guess that we should all say goodby to nose and try to move to nose2

Meanwhile, somewhere in the nose start script I have added the following hack. It just put back the aliases :)

    for member in ['Callable', 'Iterable', 'Sequence']:
        if not hasattr(collections, member):
            setattr(collections, member, getattr(collections.abc, member))
