I've spent hours (days) trying to install PySide on a macOS sierra with no success. I read and followed many explanations given by google search, including threads on stackoverflow.

My latest attempt is using pip:

pip install PySide

But I'm getting a bunch of errors: The 1st one is:

Qt QTGUI library not found.
Qt QTXML library not found.
Qt QTCORE library not found.
CMake Error at ApiExtractor/CMakeLists.txt:82 (qt4_add_resources):
Unknown CMake command "qt4_add_resources".


-- Configuring incomplete, errors occurred!

error: Error configuring shiboken

----------------------------------------
Failed building wheel for PySide
Running setup.py clean for PySide
Failed to build PySide

And the last one is:

Command "/usr/local/opt/python/bin/python2.7 -u -c "import setuptools, tokenize;file='/private/var/folders/jn/_85_tmmn3bjgrfdprd_l2c640000gn/T/pip-build-rjWn4w/PySide/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /var/folders/jn/_85_tmmn3bjgrfdprd_l2c640000gn/T/pip-1xbkki-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/jn/_85_tmmn3bjgrfdprd_l2c640000gn/T/pip-build-rjWn4w/PySide/

Is this enough information to explain the problem? I guess my question is (are): what am I doing wrong? How can I make this work? (install Pyside for python 2.7, qt5, macOS sierra.)

Please let me know if I need to give other info in order to be helped in some way.

Any help would be greatly appreciated!

Thanks,

Stefan

I assume you already checked this thread on SO, where is stated that macOS sierra is not supported. Still you can try minigeeks solution. Also have a look at the wiki of pyside. If you did not already try, install homebrew and do the following: 

brew install qt5 cmake libxslt libxml2

  • Thanks @LaughU. I did read this thread and and tried the command you mention, but i'm getting 'links' error that i don't know how to fix exactly without breaking anything else. I edited the original question and added the links part. – Stefan Gaillot Apr 24 '17 at 23:12
