Cannot build with pip 20.1

[tlhastings]

In pip 20.1, I am unable to install python-kadmin. Here is my output:

(venv) [ec2-user@<redacted> ~]$ pip install python-kadmin
Collecting python-kadmin
  Downloading python-kadmin-0.1.2.tar.gz (56 kB)
     |████████████████████████████████| 56 kB 2.1 MB/s
ERROR: More than one .egg-info directory found in /tmp/pip-pip-egg-info-l_xig4fv

It is referenced in this issue on pip that installing two packages from a single setup.py file is not supported, which I would guess is the cause here seeing as there are two 'setup' objects defined in this project's setup.py:

pypa/pip#8201

My environment:
RHEL 8, Python 3.7.7, Pip 20.1

Hi, I am also facing the same issue with Python2.7, Is there any workaround proposed for this issue?

(venv) test@virtual-machine:~$ pip --version
pip 20.1.1 from /home/test/venv/lib/python2.7/site-packages/pip (python 2.7)
(venv) test@virtual-machine:~$

[tucked]

I think #59 fixes this.
