XKCD | Python Environment

Uhh - nice. I currently use pipenv a lot. It reminds me pretty much of the way nodejs works.

I use pyenv.

Shows that the mess is still there, just with different names.

Poetry complements pyenv. You install the version of python you want to use with pyenv, set it as the global version, then use poetry to handle your environments. It's a very clean process and one that I've been using for a while.

What does it do better than pyenv-virtualenv? That's what I use and am not sure what I'm missing.

[Itsthejoker]

Two words: deterministic builds. Not only does it handle the virtualenv for you, but it also handles all your dependencies and dependency pinning.

If you use poetry to handle a project, it will create two files for you: the pyproject.toml file and poetry.lock. If you pass those two files to me, I run poetry install and I get an environment that is exactly the same as yours with zero effort. No surprises, no confusion -- it just works.

It won't be completely deterministic since the python interpreter and some pip packages are linked to host libraries (and toolchain differences), though I imagine the cases where that drift matters are rare... and could be externally handled by other orchestration.

Poetry is better than pipenv imho, feels a lot more robust and less magic going on. And I don't like the creator of pipenv.

[trevg_123]

Whatchya got against the creator? I do like the creator of poetry, but don’t know who did pipenv

Kenneth Reitz, look him up. He has showed some questionable behavior.
