cd one level above your django checkout, and launch a python shell.

Calling django_file_prefixes will fail:

{{{#!py
>>> import django
>>> django.__file__ is None
True
>>> from django.utils.deprecation import django_file_prefixes
>>> django_file_prefixes()
Traceback (most recent call last):
File "<python-input-1>", line 5, in <module>
django_file_prefixes()
~~~~~~~~~~~~~~~~~~~~^^
File "/Users/jwalls/django/django/utils/deprecation.py", line 18, in
django_file_prefixes
return (os.path.dirname(file),)
~~~~~~~~~~~~~~~^^^^^^
File "<frozen posixpath>", line 178, in dirname
TypeError: expected str, bytes or os.PathLike object, not NoneType
}}}
----
How I found this was by testing deprecation warnings, so what I'm
concluding is that deprecation warnings might crash in 6.0 if you import
Django by namespace.
