Python Dependency satisfied but pip still complains for zope.interface==4.6.0

While installing all the packages, I am getting no matching version error for zope.interface package even though the version is present in the list.

ERROR: Could not find a version that satisfies the requirement zope.interface==4.6.0 (from versions: 3.3.0b1, 3.3.0b2, 3.3.0, 3.3.0.1, 3.4.0b1, 3.4.0, 3.4.1, 3.5.0, 3.5.1, 3.5.2, 3.5.3, 3.6.0, 3.6.1, 3.6.2, 3.6.3, 3.6.4, 3.6.5, 3.6.6, 3.6.7, 3.6.8, 3.7.0, 3.8.0, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.5, 4.1.0, 4.1.1, 4.1.2, 4.1.3, 4.2.0, 4.3.0, 4.3.1, 4.3.2, 4.3.3, 4.4.0, 4.4.1, 4.4.2, 4.4.3, 4.5.0, 4.6.0, 4.7.0, 4.7.1, 4.7.2, 5.0.0, 5.0.1, 5.0.2, 5.1.0, 5.1.1, 5.1.2, 5.2.0, 5.3.0a1, 5.3.0, 5.4.0).
ERROR: No matching distribution found for zope.interface==4.6.0

As seen above the version to-be-installed is present in the from-versions list but pip still complains and errors out.
What is going wrong here ?
I am on Python 3.9.5 with pip 21.1.1

I just resolved a similar thing. You didn't paste this as part of your error message, so we may be different, but just in case:

The causative issue for me here was related to setup tools. Specifically, in the error output, I got an error ending with ImportError: cannot import name 'Feature' from 'setuptools'.

It appears that zope.interface<5.0.0 relies on a deprecated API from setuptools, so pip throws away the matching distribution once it errors out. Pinning setuptools to version 45, or using zope.interface==5.0.0 or later, should resolve this.

See https://github.com/pypa/setuptools/issues/2017.
