2021.11.5.post0, ubuntu 20.04: pipenv broken

On Ubuntu the pip version is… special. In a way that breaks the new pipenv release:

$ pipenv lock
/usr/share/python-wheels/requests-2.22.0-py2.py3-none-any.whl/requests/__init__.py:89: RequestsDependencyWarning: urllib3 (1.26.6) or chardet (3.0.4) doesn't match a supported version!

On our CI environment, we run pipenv lock [--dev-only] --requirements which breaks in a similar manner, loading the shim for Link; the end of that traceback looks like this:

  File "/usr/local/lib/python3.9/dist-packages/pipenv/core.py", line 1255, in do_init
    do_install_dependencies(
  File "/usr/local/lib/python3.9/dist-packages/pipenv/core.py", line 790, in do_install_dependencies

    r = FileRequirement.from_pipfile(name, pipfile)
  File "/usr/local/lib/python3.9/dist-packages/pipenv/vendor/requirementslib/models/requirements.py", line 1794, in from_pipfile
    link_info = cls.get_link_from_line(uri)
  File "/usr/local/lib/python3.9/dist-packages/pipenv/vendor/requirementslib/models/requirements.py", line 1551, in get_link_from_line
    link = create_link(
  File "/usr/local/lib/python3.9/dist-packages/pipenv/vendor/requirementslib/models/utils.py", line 120, in create_link
    return Link(link)
TypeError: 'NoneType' object is not callable

Up until version 2021.5.29, things were working without issue.

Steps to replicate

I can reproduce the issue the easiest in a docker container; the following commands pull Ubuntu 20.04 and install python 3.9 from deadsnakes. It’ll ask to set up a timezone in the process:

docker run --rm -it ubuntu:20.04 /bin/bash
apt update
apt install -y software-properties-common
add-apt-repository -y ppa:deadsnakes/ppa
apt update
apt install -y python3.9 python3.9-distutils python3-pip
python3.9 -m pip install pipenv

This sets you up with:

# python3.9 -m pip -V
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.9)
# pipenv --version
/usr/share/python-wheels/requests-2.22.0-py2.py3-none-any.whl/requests/__init__.py:89: RequestsDependencyWarning: urllib3 (1.26.6) or chardet (3.0.4) doesn't match a supported version!
pipenv, version 2021.11.5.post0

and running pipenv lock at that point raises the exception.

Also of note: the RequestsDependencyWarning: urllib3 (1.26.6) or chardet (3.0.4) doesn't match a supported version! output only appears with this version of pipenv; it is gone when downgrading to 2021.5.29.
