How to install pyfoam pip/python with different versions

I installed pyfoam as:
pip install PyFoam
According to https://pypi.org/project/PyFoam/ .
Now, I try to use pyFoamVersion.py and I got this message:
Traceback (most recent call last): File "/usr/local/bin/pyFoamClearCase.py", line 4, in <module> __import__('pkg_resources').run_script('PyFoam==2021.6', 'pyFoamClearCase.py') File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3251, in <module> #_call_aside File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3235, in _call_aside f(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 3264, in _initialize_master_working_set working_set = WorkingSet._build_master() File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 583, in _build_master ws.require(__requires__) File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 900, in require needed = self.resolve(parse_requirements(requirements)) File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 786, in resolve raise DistributionNotFound(req, requirers) pkg_resources.DistributionNotFound: The 'PyFoam==2021.6' distribution was not found and is required by the application
I tried this:
pip --version pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
and
python --version Python 2.7.18
How to solve this mess?

I'm on python 3.7.5
How can I resolve this? I already went and deleted pip and reinstalled it, but the same error occurs.

3.5 hours in and still cannot install Django - my fortitude is waning

Hi and thank you for taking time out of your day to read this, and I very much appreciate any assistance.
I'm trying to install Django for the first time - on a mac, python 3.7.7. However, the packages seem to be looking for 2.7 which is not the intended v3.
I understand the best practice is to install this via a virtual environment. I am currently following this link. Installed the package via sudo pip3 install virtualenvwrapper
When I run mkvirtualenv my_django_environment
I get this error:
Traceback (most recent call last):
File "/usr/local/bin/virtualenv", line 6, in <module>

Running vim ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
export PROJECT_HOME=$HOME/Django
source /usr/local/bin/virtualenvwrapper.sh
Any guidance would be most appreciated!
I previously tried to install virtualenv via easy_install -m virtualenv Could there be some confusion?

My must earnestly confess I do not know why my set up did not work.
However, I followed this tutorial which used brew and python3 -m venv. I then carried on installing Django and it worked great.
