I use PEP440 version strings, but they're not semver strings.
I feel sorry for you
[...]
I think they mean that instead of e.g. https://pypi.org/project/six/
just showing `pip install six`, it should also show example
install_requires values. E.g. `install_requires: ['six~=1.14.0']`.
Or maybe a dropdown where you select the compatibility you want and
and it formats the version string.
This does seem like a good way to encourage people to specify or at
least think about versioned dependencies, although I wonder how many
people look at pypi when specifying their dependencies in
`install_requires`?
-1. I don't want everyone to pin to an exact version just because it's
the obvious copy/paste command. That's what happens all the time in
the Node.js world, and the result is a constant battle to get everyone
to upgrade their packages, because they've unnecessarily pinned them.
Instead, encourage everyone to install *without* version numbers. If
that results in a package being broken because of a
backward-incompatible change, that's the fault of the package, and it
SHOULD be seen as a problem.
I'm with Chris here. Install without versions unless you've s specific
requirement such as a feature to use or a bug/misfeature to avoid.
I look on pinning as a tool for reproducability; if I've tested
against my venv happily, my build/install should use the versions from
its "pip freeze".
I still think PyPI should suggest/encourage using at least >= by
default. for comparison Rust/Cargo enforces semver and altho you specify
a dependency like tokio="0.2" it'll actually use any compatible version
as defined by semver.
there are many reasons to at least specify a minimum version. I see the
reasons not to specify maximum versions tho.
