How to make Jupyter notebook use PYTHONPATH in system variables without hacking sys.path directly?

Question

Same problem as in this question sys.path different in Jupyter and Python - how to import own modules in Jupyter?. In pure Python, it prepends my system environment variable

Answer 1

--Just chiming in here since the accepted answer didn't give the complete solution--

You can add the path to your modules to the JUPYTER_PATH environment variable, just the same as you would for modifying the PYTHONPATH environment variable:

export JUPYTER_PATH="${JUPYTER_PATH}:/path/to/add/here/"

If you're on a Mac or other Unix system, you would just drop the above line into your ~/.bash_profile

Hint: make sure you run source ~/.bash_profile to enact the changes and close and restart your jupyter notebook.
