How to improve Python packaging, or why fourteen tools are at least twelve too many (chriswarrick.com)

I stumbled upon this while researching package management options for python, and found it a really interesting read.

I like python as a language but this mess is something that needs to be addressed for me to consider python for future projects. I can't imagine how confusing it must be for new users.

It would be interesting to hear what you mean about the lock file being updated. Many Poetry commands should and do touch the lock, like poetry add or poetry update, but of course poetry installshould leave it untouched.

But if I want to add a single new dependency, then I probably don’t want all the rest updated at the same time

[–] coffeewithalex 2 points 1 year ago (1 children)

That can't be achieved due to dependency compatibility. What if you installed y==1.4, and froze it for a while, and then you install x==3.2, and it depends on y==1.5 or later?

pyproject.toml defines dependency restrictions, so it will be in accordance with that, but the lock file will change every time you add/remove dependencies. Naturally.

I don’t find that behaviour natural unless there is a hard conflict or I request it. So I guess it’s just a philosophical difference that led me to having a bad tint with it.

If you use poetry add it should only update what is necessary, and you can use poetry lock --no-update to lock without updating everything.
