Using FileBasedCache in Django 2.2.12 with Python 3.7.3 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.
