Pipenv is issuing false conflicts when trying to install libs

[frenetic]

In a brand new environment Im trying to install django = "==1.8.19" and django-redis = "==4.4.4".
However, Pipenv warns a conflict:
Could not find a version that matches django==1.8.19,>=1.11.

The thing is: django-redis at version 4.4.4 has no dependency on Django, as we can see here: https://github.com/niwinz/django-redis/blob/4.0.0/setup.py#L19
On the other hand, django-redis at the current release (4.9.0) and on master has a dependency on Django 1.11, as we can see here: https://github.com/niwinz/django-redis/blob/4.9.0/setup.py#L24

I think Pipenv is "looking" at the wrong versions, or is getting the wrong information, when trying to create the lock file.

Using version 11.7.4

---

Expected result

Pipenv should allow me to install Django at version 1.8.19 and Django-redis at version 4.4.4

Actual result

Pipenv says there is a conflict on Django versions, even though django-redis at version 4.4.4 has no dependency on Django.

Steps to replicate

In a brand new directory:

1. pipenv install django==1.8.19
2. pipenv install django-redis==4.4.4

reproduced. Wonder if it is not in the same scope than #1732 (transitive dependency resolution problem)

[gsemet]

indeed, so i think the behavior is normal

[kennethreitz]

the first thing it does is look for django

[kennethreitz]

got it!

[kennethreitz]

use 11.8.0 :)

[frenetic]

Im sorry to get back to this, but this bug was not fixed.

Using the newest 11.8.0 version I created a new directory and did a simple pipenv install django-redis==4.4.4. It is asking for the latest Django version, even though django-redis at version 4.4.4 does not declare this requirement.

The weird part is, even though it checks for Django, it is not listed as its dependency on pipenv graph.

Finally, in this same directory that I installed django-redis==4.4.4, if I try to install Django in a version < 1.11, I still get the dependency error.

[kennethreitz]

Definitely thought I fixed this last night. Will have to inspect.
