Install PyQt5 to Mac OS X Yosemite with python3
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 "" or any other new version of qt for mac and install it.
3. Download SIP sources here:
4. Download PyQt5-gpl sources here:
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 -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 --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

Thanks for the guide! Python/PyQt is eating on my nerves by now and your guide has taken me a step further. I keep getting this when trying to setup PyQt:
"Error: Make sure you have a working sip on your PATH or use the --sip argument".
Command line: python3 --qmake ~/Qt/5.4/clang_64/bin/qmake --destdir /usr/local//Cellar/python3/3.4.2_1/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
The path is the same as given in the previous step. Any idea on how to work this out?

Found the proper path when running make install for sip.
This worked: python3 --sip=/usr/local/Cellar/python3/3.4.2_1/Frameworks/Python.framework/Versions/3.4/bin/sip

thanks very much!
there is one place that may need update. (Due to Qt version number change)

if anybody encounters error: error: '/Users/xxx/Qt5.3.2/5.3.2/clang_64/bin/qmake' is not an executable

S/he should change it to error: '/Users/wangyu/Qt5.3.2/5.3/clang_64/bin/qmake' is not an executable

or any path qmake actually lives.


ahhh crap! I somehow managed to download SIP files (through the different way). But i can't install PyQt5 files..? why, what is my problem?


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?

vityafx commented Apr 4, 2016

@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
