what worked for me was: download the zip of the repo and unzip. Open the pyobjus folder in terminal and run this command: python setup.py install

@vik748. Thanks, but it works for you. So it’s really just sanderlands issues that are unresolved?
He installed from master, not pypi, so I assume it’s fixed and just not released. Hence my suggestion of releasing said fix.

This issue got fixed by https://github.com/kivy/pyobjus/commit/a10564c1ad3187518cc68855f9a6395e66aa08d1
Building from master should work. It simply needs a release.
