no module named pip.req

setup.py seems to currently suffer from this problem, will need to fix it at some point.

Got the same problem using python 3.7.0 (Anaconda).

how can this be circumvented? I have the same installation issue with Python 3.8 and anaconda.
The try/except block suggested as fix on stackoverflow above seems already implemented in setup.py (https://stackoverflow.com/a/49867265).

I would be satisfied to merge a PR moving the requirements into the setup.py file, as in this repo.

thanks for the pointer, this seems to do the trick on my system but it is also the first time that I am fiddling with a setup.py file.
I also needed to install manually libudunits2-0 on Ubuntu to make cfunits happy.

Yes, adding cfunits support broke the package CI testing since libudunits has to be installed manually. I was thinking of removing it (or making it optional) back when I (mostly) stopped working on this code.
