I get the same error on Mac OS X 10.10.5 with python3.5:

This has been fixed, see the latest commit history. Update to the latest revision and build with --ignore-git, otherwise you always get the old 1.2.2 version. 1.2.3 has not yet been tagged.

I'm getting the same error on OSX today with 1.2.4. Installing from pip. :(

Pyside is very old by now. You can install the latest version via pip install pyside6.
