We had some issues in our CI where pipenv would sometimes fail to sync. It has recently gotten better, I think due to a fix of some race condition due to parallel installation. I think venv would be better suited for CI in general, since it allows the use of a simple requirements.txt file.
The other thing is I think it is rather slow, at least on windows which most of my team uses.
To conclude, I think as long as you aren’t having any trouble and it simplifies your environment, you might as well use it.
I only use python as a go-to scripting language when I need to quickly automate something or write a quick throwaway script that requires an SDK, since there’s a python library for almost anything and doing it in powershell would be too much aditional work. But it does make sense that for CI you only need to figure out the venv setup once and you’re done, so it may be a better solution.
