Switching Pip to Uv in a Dockerized Flask / Django App

2025 and python packaging and dependencies management is still a mess.

It's only a mess because not everyone has adopted uv yet (IMO)

Python package management is a classic example of xkcd #927, and the community cannot be blamed for developing a Pavlovian response when it comes to yet-another-package-manager that promises to be the final solution.

UV looks very promising but I can assure you, if everyone adopted it tomorrow we would see a long tail of scenarios that UV does not work well for.

Yes, it's a mess (New: now with Rust!)

I would love to see that happen and see how astral responds. I would love to see uv get built into Python 4

Yep. The lesson is to get this right early in your language design. Do not punt until version 2.0. Think twice before putting the package/module/whatever metadata in an executable script. If you do decide to do that, think a third time. It works out better for some languages (like Common Lisp) than others (like Python).

I am perfectly content for a 90% solution, we should not let the perfect be the enemy of the good.

never had a problem with dependencies. how is it a mess? you have requirements.txt and venv per project. doesn't get easier than that

It’s a mess because there’s no first party, properly thought out and working solution.

So every year we get a new “new way” to do it. Like that xkcd… this time this is the standard that will work!
