poetry gave us lock files and consistent installs for years. uv is much, much faster however.

I used poetry professionally for a couple of years and hit so many bugs, it was definitely not a smooth experience. Granted that was probably 3-4 years ago.

I always loved poetry but then I’d always run into that bug where you can’t use repos with authentication. So I’d always go somewhere else eventually.

Some time ago I found out it does work with authentication, but their “counter ascii animation” just covers it… bug has been open for years now…

The very first time I tried to use Poetry I ran into a bug where it couldn't resolve some simple dependencies.

uv actually works.

I started using poetry abiut 4 years ago and definitely hit a lot of bugs around that time, but it seems to have improved considerably. That said, my company has largely moved to uv as it does seem easier to use (particularly for devs coming from other languages).

I've occasionally run into performance issues and bugs with dependency resolution / updates. Not so much recently, but at a previous company we had a huge monorepo and I've seen it take forever.

There was pipenv before that too, which also had a lockfile.

Funny how these things get forgotten to history. There's lots of prior art when it comes to replacing pip.

edit: here's an HN thread about pipenv, where many say the same things about it as they are about UV and Poetry before https://news.ycombinator.com/item?id=16302570

Except pipenv was never anywhere near as good. It meant well but never delivered.

Exactly I jumped onto pipenv, poetry, and pyenv as soon as I heard about them, and though they provided advantages, they all had significant flaws which prevented me being able to give full-throated endorsement as the solutions to Python environments

However, I have zero reservations about uv. I have not encountered bugs, and when features are present they are ready for complete adoption. Plus there's massive speed improvements. There is zero downside to using uv in any application where it can be used and also there are advantages.

and pip-compile before that.

Agree that uv is way way way faster than any of that and really just a joy to use in the simplicity

I have to agree that there were a lot of good options, but uv's speed is what sets it apart.

Also the ability to have a single script with deps using TOML in the headers super eaisly.

Also Also the ability to use a random python tool in effectively seconds with no faffing about.
