Install PyQt5 to Mac OS X Yosemite with python3

install script

This snippet tested on Yosemite 10.10.1

1. Define your python3 directory (for example, "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/")
2. Download "http://download.qt-project.org/official_releases/qt/5.3/5.3.2/qt-opensource-mac-x64-clang-5.3.2.dmg" or any other new version of qt for mac and install it.
3. Download SIP sources here: http://www.riverbankcomputing.com/software/sip/download
4. Download PyQt5-gpl sources here: http://www.riverbankcomputing.com/software/pyqt/download5
5. Go to your downloads by terminal (for example, "cd ~/Downloads")
6. tar xvf PyQt-gpl-5.3.2.tar.gz
7. tar xvf sip-4.16.4.tar.gz
8. cd sip-4.16.4/
9. python3 configure.py -d /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3//site-packages --arch x86_64
10. make
11. sudo make install
12. sudo make clean
13. Change line "!host_build:QMAKE_MAC_SDK = macosx10.8" to "!host_build:QMAKE_MAC_SDK = macosx10.10" in ~/Qt5.3.2/5.3/clang_64/mkspecs/qdevice.pri 
14. cd ../PyQt-gpl-5.3.2/
15. python3 configure.py --destdir /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages --qmake ~/Qt5.3.2/5.3.2/clang_64/bin/qmake
16. make
17. sudo make install
18. sudo make clean

What error's are you getting, frozenyeti?

thanks very much!

but I can't understand the first step " 1. Define your python3 directory ",

what should I do for the first step?

@wxyBUPT you need just to find out where is site-packages directory of your python3 installation. If you have few, you must remember it somehow and use in the steps below, for example, create an environment variable $SP_PYTHON_DIR=...(your dir). It is only needed for next steps (15 step).

Thanks for the guide.

If installing on 10.10.4 make sure to change macosx10.8 to macosx10.10.11 on step 13

Ok, this worked for my macOS 10.12.2 / Qt 5.80 / PyQt5.7.1 / sip 4.19 / Python3.5 installation up until step 13.

The file ~/Qt5.3.2/5.3/clang_64/mkspecs/qdevice.pri however did not contain any !host reference and simply adding it myself did not help.

Then I found this post on Stack Overflow. It stated I should run:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

which worked like a charm all the way up to step 15.

During step 15 however, I received the error:

This is the GPL version of PyQt 5.7.1 (licensed under the GNU General Public
License) for Python 3.5.3 on darwin. Error: This version of PyQt5 and the commercial version of Qt have incompatible licenses.

I was able to fix that error by commenting out some lines in PyQt5 configure.py as instructed here.

Then, I continued and the command from step 15 executed without a problem.

However, now, when I run make (step 16) I am receiving this error:

~/Downloads/PyQt5_gpl-5.7.1/QtCore/sipQtCoreQt.cpp:1093:62: error: no member named 'WindowCancelButtonHint' in namespace 'Qt'; did you mean

~~~~~~^
2 errors generated.
make[1]: *** [sipQtCoreQt.o] Error 1
make: *** [sub-QtCore-make_first-ordered] Error 2

Does anyone have any idea how to fix this?

Edited the sipQtCoreQt.cpp and removed the 2 offending lines.

This worked fine on ubuntu.

This patch gave me the confidence that I wasn't totally messing up my computer.
