Virtual environment base folder is not add to sys.path on Linux

[AbdelrahmanMSaid]

Hi,

I have a couple of questions about virtual environments. I use venv to create my environments. When I do that in Windows and I print sys.path using the environment's python executable, I get the base folder of the environment as one of the included paths. However, when I do the same in Linux, the base folder is not included in sys.path.

This means that, if I have the following project structure:

Output:
my_app
|_ my_package
   |_ __init__.py
   |_ my_module.py
|_ __init__.py
|_ main.py

...and I use this code from my_app.main import my_func inside the my_module.py file, the code will execute properly under Windows, but I will get ModuleNotFoundError if I run it under Linux.

The way I solve this issue is by adding a *.pth file, that includes the path to the base folder, in the site-packages folder of the virtual environment.

Here are my questions:

1) Why does venv behave differently, in this case, between Windows and Linux?
2) Is the solution I am using good or is there a better way of doing it that doesn't involve me having to append the path in every single *.py file?

Thank you very much.
