Dependencies missing when installing pydantic 2.7.1 using Poetry via legacy PyPI API https://pypi.org/simple about pydantic HOT 4 CLOSED

Interestingly, installing Pydantic 2.6.4 via https://pypi.org/simple does include all the dependencies, so this appears to be a regression of some sort.

[tool.poetry]
name = "test"
version = "0.1.0"
description = ""
authors = []
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.10"
pydantic = {version = "2.6.4", extras = ["email"]}


[[tool.poetry.source]]
name = "PyPI-public"
url = 'https://pypi.org/simple'

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Duplicate of #9249, #9226

Chasing down the rabbit hole of links to other issues, I end up here with the claim that:

For those that don't want to read through the other issues, the fix is to make sure that both poetry and (in my case) pkginfo are up to date

But I am using the latest released version of Poetry.

$ poetry --version
Poetry (version 1.8.2)

If maintainers are confident this is really a poetry bug, and not something that should be resolved in the packaging of Pydantic, then we should close this issue as a duplicate.

My temporary workaround has been to explicitly list Pydantic's dependencies as top level dependencies for our project.

This comment suggests poetry self add pkginfo>=1.10.0 and that does seem to resolve the issue for me locally, but need to figure out the best way to apply that in the CI pipeline.

Closing this issue.
