Why does Python not find my modules when invoking from the command line as opposed to from PyCharm?

Question

Invoking my script works fine from within PyCharm

Project structure is as follows:

project_name
└── src
    ├─ bin
    │  └─ file_to_run.py
    └─ some_module
       └─ __init__.py

I'm invoking the script from command line with

C:\path\to\venv\python.exe C:\foo\project_name\src\bin\file_to_run.py

and it gives me

ModuleNotFoundError: No module named 'some_module'

I've tried setting various values for %PYTHONPATH% including

• cd project_name && set PYTHONPATH=.
• set PYTHONPATH=C:\foo\project_name\src
• set PYTHONPATH=C:\foo\project_name\src\bin
• set PYTHONPATH=C:\foo\project_name\src\some_module
• set PYTHONPATH="C:\foo\project_name\src\some_module; C:\foo\project_name\src\some_module"

and basically all of the combinations thereof, with quotes, without quotes, separated by colons and semicolons.

I've set a sources root in PyCharm, and when I run it in the IDE it has a script path, environment variables and working directory defined as well as the options 'add content roots' and 'add sources roots' 'to PYTHONPATH' checked.

I can't think of any more relevant information as to why it can't find that module.

Windows version 10, using the command prompt.

It looks like I wasn't activating my virtualenv before running so the python version was different as suggested by @furas.
