==========================
Unsupported Python version
==========================
This version of Requests requires at least Python 3.7, but
you're trying to install it on Python 2.7. To resolve this,
consider upgrading to a supported Python version.

If you can't upgrade your Python version, you'll need to
pin to an older version of Requests (<2.28).
