Different behavior between conda- and pip-installed PySide6 #164

Closed hoechenberger closed 1 year ago

hoechenberger commented 1 year ago

Solution to issue cannot be found in the documentation.

Issue

Trying to run the following MWE succeeds when installing PySide6 from PyPI via pip, but fails with the version from conda-forge:

from PySide6.QtCore import Qt
Qt.CTRL | Qt.Key_Y

Reproducible MWE via PyPI package (works):

❯ mamba create -y -n test python
❯ mamba run -n test pip install pyside6
❯ mamba run -n test python -c "from PySide6.QtCore import Qt; Qt.CTRL | Qt.Key_Y"

Reproducible MWE via conda-forge package (fails):

❯ mamba create -y -n test python pyside6=6.4.1
❯ mamba run -n test python -c "from PySide6.QtCore import Qt; Qt.CTRL | Qt.Key_Y"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: unsupported operand type(s) for |: 'Modifier' and 'Key'

ERROR conda.cli.main_run:execute(49): `conda run python -c from PySide6.QtCore import Qt; Qt.CTRL | Qt.Key_Y` failed. (See above for error)

How can this be?

Hello, I'm still seeing this issue with the latest builds, and I'm very much at a loss as to what's going on :( This problem makes it impossible for me to use a package (MNELAB) that was developed & tested by its creator using PySide6 from PyPI, as the code behaves differently with PySide6 from conda-forge.

@jschueller would you happen to know what's happening here?

cbrnr commented 1 year ago

Maybe the new enum system introduced with 6.4 is somehow disabled in the conda build?

jschueller commented 1 year ago

it comes from the PySide6/support/ submodule that is not installed by cmake, but present only in pip https://bugreports.qt.io/browse/PYSIDE-2183

hoechenberger commented 1 year ago

Thank you for filing this bug, @jschueller!
