Package name causes issues when combining requirements

[Jorricks]

BUG/PROBLEM REPORT (OR OTHER COMMON ISSUE)

What I did:

I created a small setup.py and listed a package that has zope-interface==5.4.0 as requirement. I used pip-tools to compile the package, which leads to zope-interface==5.4.0 being added.
When I install the package I get

Requirement already satisfied: zope-interface==5.4.0 in /Users/jorrick/my_venv/lib/python3.8/site-packages (5.4.0)

Then when I try to run my entry_point console_scripts, I get

pkg_resources.DistributionNotFound: The 'zope-interface==5.4.0' distribution was not found and is required by my_package

But when I run pip3 freeze, I get

zope.interface==5.4.0

What I expect to happen:

That I am able to run my CLI commands without issues

What actually happened:

It throws a DistributionNotFound error.

What version of Python and Zope/Addons I am using:

Python3.8
zope.event==4.5.0
zope.interface==5.4.0

on MacOs

The package has the name `zope.interface` (not `zope-interface`).

Yess I think you are right and I need to take this up with pip-tools instead of this repository.

Opened jazzband/pip-tools#1599 with pip-tools

This is a constant struggle, because, according to PEP 503, . gets normalized away to - for purposes of interacting with PyPI indexes. But that normalization is often inconsistently applied or applied to places it shouldn't be.

$ pip -vv index versions zope.interface
