So you are on a debian based system? That really puzzles me because I never had
any trouble of installed packages not being importable.
Now before I go on and suggest that you do a clean installation of your distro,
I decided to try pysim myself on my current debian testing system.
I get this:
▶ ./pySim-read.py
Traceback (most recent call last):

from cmd2 import CommandSet, with_default_category, with_argparser
ImportError: cannot import name 'CommandSet' from 'cmd2'
(/usr/lib/python3/dist-packages/cmd2.py)
after I did this:
git clone ssh://go/pysim
cd pysim/
sudo apt-get install python3-pyscard python3-serial python3-cmd2 python3-construct
sudo pip3 install pytlv
sudo pip3 install jsonpath-ng
▶ python3 --version
Python 3.9.2
So I'm also having problems.
Resolving them:

ModuleNotFoundError: No module named 'colorama'
I would expect that a generic text prompt library would be able to at least
*start* without color support installed.
(but later on I find out the debian testing version of cmd2 is super old)

ImportError: cannot import name 'CommandSet' from 'cmd2'
(/usr/lib/python3/dist-packages/cmd2.py)
Installed by the debian-testing package is cmd2 version 0.8.5.
The CommandSet class was added in June 2020 in cmd2 1.3.0.
▶ sudo apt-get remove python3-cmd2
▶ sudo pip3 install cmd2
Successfully installed cmd2-1.5.0
So pip3 gets me the latest version of cmd2.
After that, pySim-read.py starts successfully.
But I get this:
▶ ./pySim-read.py -p 0
Using PC/SC reader interface
Card reader initialization failed with exception:
'Failure to establish context: Service not available.'
I remember this, I need to start the PC/SC service or something. I thought it
said so so in the README, alas no such hint is there. So I figure out myself
that it has to be
▶ sudo apt-get install pcscd
▶ sudo systemctl start pcscd
Now I can successfully pySim-read.py my new sysmoISIM-SJA2,
but right in the end there is an error again:
▶ ./pySim-read.py -p 0
Using PC/SC reader interface
Reading ...

Done !

So I am also having problems, but it is a different class of problem that
Niels-with-i is seeing, because it was solvable by installing the right
dependencies.
Maybe people active in the pysim.git can take this transcript of getting it
running to improve some things? Maybe mention pcscd in the README? Maybe
mention the cmd2 version required?
I'm back to osmo-bsc now.
