Issue

When trying to install PySide6 via poetry add PySide6, it fails to find a candidate for the dependency shiboken6, despite being able to install normally using pip install PySide6 within the environment. I've tried running with debug mode as noted above, but no additional helpful information is revealed.

This is probably a duplicate of #3591.

Probably the most complete ticket is this one: #3458 (assuming it is indeed the same root cause).

[furgoose]

Ah yeah I missed those issues, looks to be the same cause. This can be closed then 👍🏻
