Install Python3 and PyQt5 on mac
I switched to Python3 and PyQt5 on mac Sierra because of ImportError while importing modules from Packages. It is due to SIP (System Integrity Protection) that Apple introduced in recent OS. from PySide2 import QtGui ImportError: dlopen(/Users/usr/Others/PySide2/QtGui.so, 2): Library not loaded: @rpath/libpyside2.2.0.dylib Referenced from: /Users/usr/Others/PySide2/QtGui.so Reason: image not found Easiest way I found to install python and Pyqt is using brew and pip3 brew install python3 pip3 install pyqt5 Directory where Python3 is install /usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/bin/python3.6
