Unless you have pinned the exact version numbers in requirements.txt (which you should) or kept you conda/venv..etc around it might be hard. I know at this stage this would be too much compared to what we are talking about regarding python scripts but non-python dependencies are real painful.

I know that this is probably beyond bash scripting vs python scripting but I was just replying to how 6 months project can have problems.

Also not a 6 months scale but the python standard library definitely changes and I would take bash anytime if I have to use venv for running util scripts.

Edit: When python3.8 removed 'time.clock()' it was annoying to change that. I know that it was deprecated since 3.3 (as I remember) but this is the example I have in mind now. But probably it was before I was born that people using

start=$(date +%s%N)

end=$(date +%s%N)

And I will be dead before/if this becomes impossible to use.
