Support pathlib.Path parameter in create_dir()

See original GitHub issue

I created a repository here to show the bug I am getting: https://github.com/shuttle1987/pyfakefs-pathlib-fail

Essentially when this test is run:

def test_pathlib(fs): #fs is the fake filesystem fixture
    """Attempt to use a pathlib path"""

    import pathlib
    base_dir = pathlib.Path('/tmp/corpus_data')
    fs.create_dir(base_dir)

    from example_lib.searcher import determine_labels

The failure is as follows:

As far as I can tell from reading the documentation this library is supposed to patch pathlib.Path.

Thanks for the report! Currently, create_dir is not designed to take a Path parameter, so you have to convert it to a string first, e.g. fs.create_dir (str (base_dir)). But I agree that it would make sense to support this - I will adapt it accordingly.
