Installpyqt5osx

The following tutorial is based on Robscurity.

On the Mac OS X computer, create a folder called Sources

Downloading stuff into folder Sources:

   Download PyQt - https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.6/PyQt5_gpl-5.6.tar.gz/download

   Download sip - http://sourceforge.net/projects/pyqt/files/sip/sip-4.18/sip-4.18.tar.gz

   Download Qt - http://download.qt-project.org/official_releases/online_installers/qt-opensource-mac-x64-online.dmg

 Uncompress files:

Doubleclick on PyQt-gpl-5.6.0.tar.gz and sip-4.18.tar.gz to uncompress.

Open /Applications/Utilities/Terminal

Note 1: Don´t forget to use python3 command instead of python Note 2: I use robert as username in this example

In Terminal:

$ cd /Users/<yourname>/Desktop/Sources

$ cd sip-4.18

                 #cd into the folder sip-4.18

$ python configure.py -d /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ --arch x86_64

                 # —arch in my case is x86_64 since I have MacBook Pro. 

$ cd make

$ sudo make install
