Installation of non-required dependency

See original GitHub issue

One of my dependencies is using ruamel.yaml, which has a requirement on ruamel.ordereddict if the installation is happening on CPython <= 2.7.

This dependency does not install on Python 3, and it shouldn’t be installed – something pip honors.

Actually, pipenv honors this too, for an initial installation. However, it adds ruamel.ordereddict to the Pipfile.lock anyway, and the wheels come off there when doing a fresh installation of the pipenv. I.e.:

pipenv --rm
pipenv install --three  # now attempts to install ruamel.ordereddict, which has c bindings that won't compile.

Maybe I’m throwing edge cases at you today. But can we figure this out?

Here’s the lockfile:

And, here’s the output of pip freeze:

$ pipenv run pip freeze

So what are we supposed to make of the “fancy install process” that uses pipsi? Is that not a good approach?

I did end up installing pipsi with Python3, and that overcame my problem. But I guess --two would fail now.
