Description
Using FileBasedCache in Django 2.2.12 with Python 2.7.3 is giving ValueError: unsupported pickle protocol: 5
Checking the highest protocol version for pickle using pickle.HIGHEST_PROTOCOL is giving 4, so the protocol 5 is not available.
Line that is causing the error: filebased.py in _is_expired at line 146, exp = pickle.load(f).
Using Python 3.8.0 solves the problem.
