I'm excited to give this a shot, but I've heard this promise many times before.

I vaguely remember the exact same sentiment being expressed for both pip and Pipenv. The project I'm working on is currently migrating from Pipenv to Poetry, and while it's an improvement I have no hope that the fifth generation (setuptools, EasyInstall, pip, Pipenv, and now Poetry) Python packaging tool is in any way the last one.

I second this. Poetry is a great all-in-one tool for dependency and package management. I've written a few blog posts about it, and I remain happy with it. The Poetry team has done a great job making quality of life improvements to the tool, and it's actively maintained. It's worth checking out.

Wait, whats wrong with pip and venv with a requirements.txt file?

Yes I do, sadly, I need it for my job. I don't like it, and I want it replaced, but until then I have to commit to the decision my team has made.

Is there a better way to get a lock/freeze file that includes checksums?
