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.

Answer 1

Make sure you have homebrew installed.

Use the following commands:

1. brew tap cartr/qt4
2. brew tap-pin cartr/qt4
3. brew install qt
4. brew install pyside

Answer 2

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()
