I would advise against running Python's own packaging tools as root. Of 
course, if someone is wanting you to use the very latest of the latest 
for their software, which says something about their development 
practices, in my opinion, then an entirely separate Python installation 
can be the way to go. Alternatively, user-specific library management 
used to work with pip, which can be acceptable if you do not have 
complicated needs. See...

https://docs.python.org/3/installing/index.html

Specifically:

pip3 install --user package...

The official guidance probably suggests a "virtualenv" or "venv" or 
something similar for a separate installation, but you can fairly easily 
build and install your own Python along with library directory and then 
use that with pip. In other words, configure, make and make install with 
a prefix of your choice. Then, make sure that you invoke your own 
separate Python binary.

Just make sure that you invoke the appropriate pip3 binary. It should 
reside alongside the corresponding python3 binary in the filesystem. 
That should set up the PYTHONPATH which is the equivalent to PATH but 
for Python packages.
