#18401 attrs module mapping needs to be updated? Issue created by smsearcy Describe the bug Pants fails to resolve the dependency for

import attrs

with the following error, when

attrs

is listed in

requirements.txt

and

import attr

works:

14:19:42.52 [WARN] Pants cannot infer owners for the following imports in the target helloworld/main.py:lib:

  * attrs (line: 4)

The attrs class now provides two import packages (as of v21.3.0):

attr

and

attrs

. Thus, I think the

DEFAULT_MODULE_MAPPING

for

attrs

in

src/python/pants/backend/python/dependency_inference/default_module_mapping.py

needs to be updated to include both. I was able to workaround the issue by adding the following directive to the

BUILD

file:

python_requirement(
    name="attrs",
    requirements=["attrs>=21.3.0"],
    modules=["attrs"],
)

Pants version 2.15.0 OS Ubuntu Linux (WSL). Additional info I was able to replicate the issue by cloning https://github.com/pantsbuild/example-python and making the changes published in this gist. pantsbuild/pants
