ImportError for implicit namespace (pyproject, setuptools) #7875
Description
Bug description
Hi all,
I try to run pylint on an implicit namespace that is build from a pyproject.toml with setuptools as backend. However, pylint is not able to deduce the namespace and throws an ImportError.
Project lay-out:
|-- pyproject.toml |-- src |-- foo |-- bar |-- __init__.py |-- fun.py pyproject.toml
[build-system] requires = ["setuptools", "setuptools-scm"] build-backend = "setuptools.build_meta" [project] name = "foo.bar" version = "0.0.1"fun.py
def foo() -> None: passConfiguration
No response
Command used
pip install . pylint foo.barPylint output
