Import from my package recognized by PyCharm but not by command line

I've created the following package tree:

/main_package
    /child_package
    version.py

where version.py contains a single string variable (VERSION)

Inside my script in child package I'm importing version.py by the following line:

from main_package.version import VERSION

While I'm running the code from PyCharm everything works great, however when I'm running the code via the command line I'm getting the following error message:

C:\Users\usr\PycharmProjects\project\main_package\child_package>python script.py
Traceback (most recent call last):
File "script.py", line 2, in <module>
from main_package.version import VERSION
ModuleNotFoundError: No module named 'main_package'

I've found in the internet that I might need to add my package to the python path, however it doesn't seems to work for me

The pythonic way is to have a setup.py file to install your project in the system (check python Minimal Structure):

from setuptools import setup

setup(name='main_package',
      version='0.1',
      description='main package',
      license='MIT',
      packages=['main_package'],
      zip_safe=False)

Then you install it as follow:

  • python setup.py install for global installation

OR

  • python setup.py develop for local installation in editable mode

PyCharm sets the Python Path at the root of the project (by default). To mimic this in a quick'n'dirty fashion, you just need to do this once in your shell session before invoking python whatever:

set PYTHONPATH=C:\Users\usr\PycharmProjects\project
