Installing NodeGraphQt requires Qt.py to be installed

[Martmists-GH]

This makes setting up applications depending on NodeGraphQt difficult, as a crash happens in setup.py:

Oddly enough this import is not satisfied even when PySide2 is already installed.

Is this still an issue? I am having some issues getting this to play nice with PyQt5.

@tristanpoland , it is not working with the module pyqt but with qt.py module. It is confusing i agree. If you run the command python -m pip install -e path_to_nodegraphqt, it will install the required dependancies. And should work immediatly

@Zelfior Thanks, that fixed it for me. The naming conventions in Python libraries in particular seem to be quite confusing, I appreciate the help!
