I have a package my_lib and want to use it in another repo in pycharm.

When I have my setup.py file

from setuptools import setup, find_packages

with open("README.md", "r", encoding="utf-8") as fh:
    long_description = fh.read()

setup(
    name='my_lib',
    version='1.0.0',
    author='Some author',
    author_email='[email protected]',
    description='',
    long_description=long_description,
    long_description_content_type="text/markdown",
    url='https://github.com/my-proj/my-lib',
    project_urls={
        "Bug Tracker": "https://github.com/my-proj/my-lib/issues"
    },
    license='Apache-2.0',
    packages=find_packages(),
    install_requires=[
        'fastapi'
    ],
)

I can install it via

pip3.12 install -e ../my-lib

and PyCharm recognizes everything

However, when I add pyproject.toml

[build-system]
requires = ["setuptools>=64", "wheel"]
build-backend = "setuptools.build_meta"

[project]
name = "my_lib"
version = "1.0.0"
description = ""
readme = "README.md"
requires-python = ">=3.10"
license = {text = "Apache-2.0"}
authors = [{name = "Some author", email = "[email protected]"}]
dependencies = [
    "fastapi"
]

[project.urls]
Homepage = "https://github.com/my-proj/my-lib"
'Bug Tracker' = "https://github.com/my-proj/my-lib/issues"

the other project does not recognize something like

from my_lib.a import b

anymore.

Do you know how to resolve that?
