[Bug]: aspect_rules_py is incompatible with rules_poetry

[luangong]

What happened?

The py_library, py_binary, and py_test rules don’t work with rules_poetry. Packages installed by poetry.parse() can’t be included as dependencies of a py_library, py_binary, or py_test target.

Version

• Development (host) and target OS/architectures: macOS on an Apple silicon Mac
• Output of bazel --version: bazel 7.1.1
• Version of the Aspect rules, or other relevant rules from your WORKSPACE or MODULE.bazel file: aspect_rules_py 0.7.3
• Language(s) and/or frameworks involved: Python, Poetry

How to reproduce

Given the following minimal example:

# MODULE.bazel
module(name = "poetry_demo", version = "0.1.0")

bazel_dep(name = "aspect_rules_py", version = "0.7.3")
bazel_dep(name = "rules_python", version = "0.31.0")

# Register a hermetic Python toolchain rather than rely on a locally-installed
# interpreter.
python = use_extension("@rules_python//python/extensions:python.bzl", "python")
python.toolchain(
    configure_coverage_tool = True,
    is_default = True,
    python_version = "3.11",
)
use_repo(python, "python_3_11")

# https://registry.bazel.build/modules/rules_poetry
bazel_dep(name = "rules_poetry", version = "0.3.4")

poetry = use_extension("@rules_poetry//python:extensions.bzl", "poetry")
poetry.parse(
    name = "poetry",
    lock = "//:poetry.lock",
)
use_repo(poetry, "poetry")

# BUILD.bazel
load("@aspect_rules_py//py:defs.bzl", "py_binary")

py_binary(
    name = "main",
    srcs = ["main.py"],
    deps = [
        "@poetry//:absl-py",
    ],
)

# pyproject.toml
[tool.poetry]
name = "poetry-demo"
version = "0.1.0"
authors = []
description = "Bazel Python example using Poetry"
package-mode = false

[tool.poetry.dependencies]
python = "~3.11"
absl-py = "^2.1.0"

# main.py
from absl import app

def main(argv):
    print('Hello, Python and Poetry!')
    return 0

if __name__ == '__main__':
    app.run(main)

The build fails with the following error message:

ERROR: poetry-demo/BUILD.bazel:3:10: in deps attribute of py_binary rule //:main:
'@@rules_poetry~~poetry~poetry//:absl-py' does not have mandatory providers:
'PyInfo' or 'PyVirtualInfo'. Since this rule was created by the macro 'py_binary',
the error might have been caused by the macro implementation

However, aspect_rules_py works with pip.parse, and rules_python works with both pip.parse and poetry.parse. Here is the compatibility table:

Extension Method	rules_python	aspect_rules_py
pip.parse	✅	✅
poetry.parse	✅	❌

[luangong]

It seems that the issue is caused by #311. I have to downgrade aspect_rules_py to 0.7.1 to work around this.

Alternatively, open an issue with rules_poetry to use the provider loaded from rules_python, rather than native as it'll hit up against this issue with other uses of PyInfo.

As a data point, rules_pycross did the same thing here, jvolkman/rules_pycross#90

I suggest to close it here as it relates to bazelbuild/rules_python#1069 (comment)

Will fix in the rules repository
