Poetry cannot import from subfolders in scripts runned by "poetry run"

Question

Project structure is like this:

.
├── README.md
├── pyproject.toml
...
my_project_name/
    ├── moduleA.py
    ├── moduleB.py
    └── FolderC
        └── moduleC.py

moduleA.py:

from .moduleB import moduleB_func
from .FolderC.moduleC import moduleC_func
...

script in pyproject.toml:

funcA_run = my_project_name.moduleA:funcA

(funcA function is just example – exception appears on start of compiling at the second line on import)

If i type poetry run funcA_run in project directory (where my_project_name folder, readme.rst, pyproject.toml and other poetry files), moduleB imports successfully, but moduleC from subfolder is not:

ImportError: cannot import name ‘moduleC_func’ from ‘FolderC’ (unknown location)

Removing . from import doesn’t help.

With import FolderC.moduleC.moduleC_func i getting

ModuleNotFoundError: No module named ‘FolderC.moduleC_func’

If moduleC.py import would be in moduleB.py, same will happen.

So, because of this i can’t run any scripts, that contains local relative imports from my project.

Poetry version is 1.1.14

EDIT: Problem as it shown in this question is unreproducable. More details in my answer.

Problem is resolved in some sense. Somewhy, poetry run requires another format of imports.

With structure like this:

├── README.md
├── pyproject.toml
...
my_project_name/
    ├── moduleA.py
    └── FolderC
        └── moduleC.py
        └── moduleC_2.py

If moduleC.py imports something from moduleC_2.py, and i import moduleC.py in moduleA.py, imports should look different if two cases:

If i run moduleA.py as script with poetry run:

# moduleA.py:
from .FolderC import moduleC.py  # with .

# moduleC.py
from .moduleC import some_func  # relatively folderC and with .

If i run moduleA.py manually with python moduleA.py:

# moduleA.py:
from FolderC import moduleC.py  # without .

# moduleC.py
from folderC.moduleC import some_func  # relatively my_project/ and without .
