I used pip install zipfile, and error went out:
Could not find a version that satisfies the requirement zipfile (from versions: ) No matching distribution found for zipfile
Addition Info: pip 18.1 from /Users/xxxx/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)
You don't need to install it. zipfile is in the Python standard library . import zipfile
should work just fine on both Python 2.7 and Python 3.7 .
