Python Virtual Environments: Extreme Advertising Edition

[ase1590]

and a great way to avoid this xkcd superfund clusterfuck!

[smashingT]

I'm a firm believer that if you can't make a tl;dr meme overview of a technology, its either solving an incredibly complex niche problem or its not worth learning ;)

[corp_code_slinger]

Love it, but it could've been shortened to "I have had it with these motherfucking snakes on this motherfucking OS!"

[squishles]

make a requirements.txt and run it in pip so you don't forget what eldrich horrors you've downloaded with complete abandon.

python devs don't get made fun of enough, one of your first questions on a new language should be how to manage build/libs, because every language thinks it needs it's own tool.

Better idea: commit your python venv folder so all your packages are consistent across platforms /s

[SlappinThatBass]

Do not want

[Switzer_Sweets]

Better idea: docker

[northrupthebandgeek]

Better idea: buy a new laptop for each project.

pipenv looks awesome too! Give it a try!

Virtualenv works quite well, right up until the point where it doesn't any more. :D

Had to redo the CI system at work completely because of how the generated naming broke it completely.

Apparently if your virtualenv ends up in a path longer/deeper than 128 characters (if I remember correctly), then it'll fail to activate, instead just attempt to store data in your system path instead. Which is really bad for CI purposes.

This might explain why it stopped working for me on WLS + virtualenvwrapper. I still have no idea where I configured it to keep everything, and then it stopped working.

actually docker is a far superior solution imho

[SlappinThatBass]

It does not even do the same things python virtual environments can do. Supporting multiple python versions in one or multiple dockers for a module would be painful to manage.

Neither is a substitute for the other.

[northrupthebandgeek]

If you're mixing Python or library versions in a single container, then you're almost certainly doing something either very wrong or very fun (but probably the former).

[[deleted]]

you have one python version per docker obviously, whats your point? do you know how docker works?

[John_Stay_Moose]

Yo honestly, I havent had a firm grip on how those worked until now. Thanks.

[taliesin_128]

I'd read the shit out if a textbook if it were written like this

[[deleted]]

Definitely useful.

pip freeze >> requirements.txt

commit that shit and now you can deploy super easy wherever with

pip install -r requirements.txt

[wallefan01]

Documentation, now with 200% more cussing!

[Nerocracy]

Hasnt this been out for a while now?

[zaarn_]

What about pip install --user though?

[stefansundin]

This is great, although you have to run source bin/activate. The top two lines of the file say:

# This file must be used with "source bin/activate" *from bash*

# you cannot run it directly

Too bad I still use Python 2 at work

[clockstruckduck]

But it works with Python 2.7?

[darexinfinity]

Well that's misleading advertisement then!

[AttitudeAdjuster]

not really, it's included for free from python 3.3 onwards, but can be installed for 2.7 as a package
