via Python pyenv

create a virtual python environment

$ python3.11 -m venv ~/.virtualenvs/se_sim

and activate it

NOTE: Depending on the shell, you can either use

• Activate.ps1

• activate

• activate.csh

• activate.fish

$ source ~/.virtualenvs/se_sim/bin/activate

now the environment is empty

$ pip list
Package    Version
---------- -------
pip        22.3.1
setuptools 65.6.3

now first install the production part of the environment

(‘git clone’ assumed and changed into the directory)

$ pip install -r requirements_prd.txt

$ pip list
Package    Version
---------- -------
click      8.1.3
pip        22.3.1
PyYAML     6.0
setuptools 65.6.3

current workaround for python to find a module that is not actually installed

export PYTHONPATH=src/

and lift off …

$ python ./src/se_sim/cli.py \
    se_sim.plugins.input.v01example.read \
    se_sim.plugins.json.out.StdOut:pretty=true
