Description Antonio Rojas 2018-07-10 21:44:04 UTC
Python plugins don't work with PyQt 5.11. For some reason beyond my understanding the PyQt developer decided that PyQt must now use a private copy of sip [1], and that seems to confuse krita, which still uses the shared sip. 

krita.scripting: "Traceback (most recent call last):"
krita.scripting: "  File \"/usr/lib/krita-python-libs/krita/__init__.py\", line 7, in <module>"
krita.scripting: "    from .api import *"
krita.scripting: "  File \"/usr/lib/krita-python-libs/krita/api.py\", line 28, in <module>"
krita.scripting: "    from PyKrita.krita import *"
krita.scripting: "RuntimeError: the PyQt5.QtCore module failed to register with the sip module"
krita.scripting: "Could not import krita"

Tried rebuilding krita with PyQt 5.11, didn't help.

I don't get it either -- please either provide a patch, or complain to Phil. I currentlly don't have a system where I can reproduce the problem, and until my distribution updates to that, I won't look into it.

Fix loading PyKrita with PyQt 5.11

PyQt>=5.11 uses its own private copy of SIP, with sipName PyQt5.sip. This causes an API mismatch with the Krita python module, which uses the default "sip" sipName, and the module fails to load. This patch fixes this by using the PyQt5.sip sipName for PyQt>=5.11
