My workflow:
By default pyvenv excludes system packages, so I can have different versions in the venv. To reset the venv, I just have to delete the .venv dir.
Seconded, after being burned repeatedly I always do this. But why are you calling activate from the directory above?
I don't think he does. If you're talking about the third line, there's a space between the dots.
The dot command is equivalent to
source(running the script in the context of the current shell).Exactly, venv solves this issues for me
I love this workflow because it has only two prerequisites: python and pip. It works on windows, linux, any vm or container. Pipenv requires some setup, while this should work everywhere. In powershell you have to use
./.venv/bin/acticate.ps1but that's the only difference.i've moved to just using conda environments. i find it's a lighter load on my old brain.
What did you not like on pipenv in comparison to venv? I was always avoiding venv because it was, as you said, manual work and it was too much effort to again google what was the order of commands and parameters to start a venv, which is not an issue in pipenv, since you just pipenv install what you need.
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.
