Please see the new repositories for standalone PySide2 wheels:
The aim of the pyside2-wheels project was to build PySide2 wheels on multiple platforms before official, portable wheels were offered by The Qt Company. The project was abandoned when PySide2 became installable via conda, making it widely available without having to build PySide2 from source. Shortly thereafter, The Qt Company announced it is under way to distribute their own pip-installable and portable wheels. Unfortunately, this still hasn't happened, and the need for standalone wheels still exist, and so I decided to open up three separate new projects (links at the top) to address this.
The old and abandoned pyside2-wheels project is now archived and will no longer be maintained. The wheels built for the pyside2-wheels project will be removed once official wheels are published by The Qt Company.
