Rye. Armin Ronacher’s take on a Python packaging tool. There are a lot of interesting ideas in this one—it’s written in Rust, configured using pyproject.toml and has some very strong opinions, including completely hiding pip from view and insisting you use “rye add package” instead. Notably, it doesn’t use the system Python at all: instead, it downloads a pre-compiled standalone Python from Gregory Szorc’s python-build-standalone project—the same approach I used for the Datasette Desktop Electron app.

Armin warns that this is just an exploration, with no guarantees of future maintenance—and even has an issue open titled “Should Rye exist?” # 24th April 2023, 4:02 am

Introducing PyPI Organizations. Launched at PyCon US today: Organizations allow packages on the Python Package Index to be owned by a group, not an individual user account. “We’re making organizations available to community projects for free, forever, and to corporate projects for a small fee.”—this is the first revenue generating PyPI feature. # 23rd April 2023, 8:29 pm

Should You Use Upper Bound Version Constraints? (via) Should you pin your library's dependencies using "click>=7,<8" or "click~=7.0"? Henry Schreiner's short answer is no, and his long answer is an exhaustive essay covering every conceivable aspect of this thorny Python packaging problem. # 5th September 2022, 5:42 pm

What to do when PyPI goes down. My deployment scripts tend to rely on PyPI these days (they install dependencies in to a virtualenv) which makes me distinctly uncomfortable. Jacob explains how to use the PyPI mirrors that are starting to come online, but that won’t help if the PyPI listing links to an externally hosted file which starts to 404, as happened with the python-openid package quite recently (now fixed). The comments on the post discuss workarounds, including hosting your own PyPI mirror or bundling tar.gz files of your dependencies with your project. # 21st July 2010, 10:19 am
