Are you sure 

% python

invokes the 3.8 interpreter?

The traceback suggests that it may be 3.7.

Try

% ./python Lib/test/test_shutil.py

or, if you have installed python3.8

% python3.8 Lib/test/test_shutil.py

If you still get an error with a path into the /usr/lib/python3.7 stdlib
have a look at the PYTHONPATH environment variable.
