Python PyQt on macOS Sierra

Question

How can I get to work PyQt 4 or 5 on a Mac with OS X Sierra? It seems that I have to wait for a new version of PyQt but I am not sure if that is actually true.

Considering PyQt4 is no longer actively supported by its creators, I'd recommend using PyQt5 (plus I found it much easier to get working). Once you've installed pip3 (you can use easy_install) run the following commands in your terminal:

1) pip3 install sip
2) pip3 install PyQt5

You can then run the following sample app to see if everything is working:

import sys
from PyQt5 import QtWidgets

def main():
    app = QtWidgets.QApplication(sys.argv)
    window = QtWidgets.QMainWindow()
    button = QtWidgets.QPushButton("Hello, PyQt!")
    window.setCentralWidget(button)
    window.show()
    app.exec_()

if __name__ == '__main__':
    main()
