I am very new to python/pip, and at this point I'm just fiddling with things, trying to get my environment installed so I can start testing the language.

I had PIP properly installed,but was trying to find something that might help me integrate an interpreter into Jetbrains PyCharm. I found something called PIPEnv (https://pypi.org/project/pipenv/) and installed it, but now it seemed to have broken PIP

You can try to uninstall pip and pip env.

Then reinstall pip and then try to again install pipenv. If this time it does not work then you need to use pip and virtualenv instead of pip env.

Uninstall both of them and this time install pip and virtualenv
You can configure pycharm to work with virtualenv.
Anyway these commands worked for me
For uninstalling 

python3 -m pip3 uninstall pip3



sudo -H pip3 install --upgrade pip
sudo -H pip3 install pipenv

Now try executing 'pipenv'
If it still does not work try upgrading your python3.
If you are still using python2.7 then replace pip3 with pip

We don't use PIPEnv but have found that the latest pip release is causing import errors in a few places in our build systems. Since the code hadn't changed since the last successful build I am strongly suspecting this pip version (19.0.2) is broken/incompatible in some way. The solution for us will be to go back to 19.0.1 which has been working fine for a while. We'll be doing this inside the virtualenv not at the system level.

I have found in this post (AttributeError: Module Pip has no attribute 'main') a patch for migrating to most recent pup versions for this import problem in some versions of pip. Making code to support but newer and older versions, the workaround for importing the pip 'main' module results as here:

if hasattr(pip,'main'): pipm=pip.main else: from pip import _internal pipm=pip._internal.main
