Personally i've never really seen the advantages any of these tools over having a requirements.txt, or slightly fancier and more modern, using a pyproject.toml file. e.g. in a recent project the entire package configuration is this pyproject.toml file: [project] name = "vera" version = "0.0.0" requires-python = ">=3.10" authors = [ { name = "Doxin" } ] dependencies = ["moderngl==5.7.3", "pysdl2==0.9.14", etc etc] [project.optional-dependencies] dev = ["pre-commit==2.20.0"] [tool.setuptools] packages = ["vera"] Getting started with development is as easy as python3.10 -m venv venv source venv/bin/activate pip install -e vera[dev] Updating packages is just rerunning the pip install command.
