Fix Python – Unresolved reference issue in PyCharm


Asked By – prosseek

I have a directory structure

├── src
│   ├──
│   ├── ...

And I can access the network module with sys.path.insert().

import sys
import os.path
sys.path.insert(0, "./src")
from networkAlgorithm import *

However, pycharm complains that it cannot access the module. How can I teach pycham to resolve the reference?

Manually adding it as you have done is indeed one way of doing this, but there is a simpler method, and that is by simply telling pycharm that you want to add the src folder as a source root, and then adding the sources root to your python path.

This way, you don’t have to hard code things into your interpreter’s settings:

  • Add src as a source content root:

  • Then make sure to add add sources to your PYTHONPATH under:

    Preferences ~ Build, Execution, Deployment ~ Console ~ Python Console

  • Now imports will be resolved:

This way, you can add whatever you want as a source root, and things will simply work. If you unmarked it as a source root however, you will get an error:

After all this don’t forget to restart. In PyCharm menu select: File –> Invalidate Caches / Restart
