NameError: name 'QMessageBox' is not defined

This is a bug in NNJoin plugin.

  • Open NNJoin_gui.py file located in "/Users/joanlee/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/NNJoin/" using an editor.

  • Add from qgis.PyQt.QtWidgets import QMessageBox line to imports section.

  • Then save the file and (you may need to) restart QGIS.


You should import QMessageBox from PyQt

from qgis.PyQt.QtWidgets import QMessageBox
