Ran into the same version dependency issue for urllib3.
pkg_resources.DistributionNotFound: The 'urllib3<1.26,>=1.20' distribution was not found and is required by botocore

Tried upgrading urllib3 but it's already up to date
Requirement already up-to-date: urllib3 in /Users/jim-mccumber/.pyenv/versions/3.7.3/lib/python3.7/site-packages (1.25.3)

Env: macOs Mojave 10.14.6
Python 3.7.3
