FabSim uses invoke==2.0.0 which does not work on Python 3.12+

Relevant logs and/or media

FabSim installs module invoke version 2.0.0. That version uses module imp, which is removed in Python 3.12 https://docs.python.org/3.11/library/imp.html

Therefore, FabSim does not work in Python 3.12
This issue was fixed in invoke: pyinvoke/invoke#675

The version is specified here:

FabSim3/configure_fabsim.py

Line 30 in 941bab7

check_call_list.append("invoke==2.0.0")

Also qcg_requirements.txt defines the old version:

FabSim3/qcg_requirements.txt

Line 33 in 941bab7

invoke==2.0.0

Platform details

• OS: Ubuntu 24.04
• Python version: 3.12.7
