Installation fails on QGIS 3.0

[m-kuhn]

Is the plugin not compatible with QGIS or is there something missing in the installation?

Couldn't load plugin 'swiss_locator' due to an error when calling its classFactory() method 

ModuleNotFoundError: No module named 'qgsfilterlineedit'

apparently there is an issue for the custom widgets one more.
can you check if you can find pythonX/site-packages/PyQt5/uic/widget-plugins/qgis_customwidgets.py?

Also which version is it (plugin)?
I switched PyQt5.uic to qgis.PyQt.uic hoping this would fix this, but apparently not. The commit was just yesterday and the release too (1.1.3)

[3nids]

otherwise, we can add the same trick than here
https://github.com/qgis/QGIS/pull/7130/files

[3nids]

should be fixed in 1.1.4

[m-kuhn]

Seems to be still problematic...

@m-kuhn can you check if you can find pythonX/site-packages/PyQt5/uic/widget-plugins/qgis_customwidgets.py ?

[3nids]

I think it might be a matter of launching QGIS with the proper PYTHONPATH.
If so, something to be fixed in OSGeo4W.

@m-kuhn can you check if you can find pythonX/site-packages/PyQt5/uic/widget-plugins/qgis_customwidgets.py ?

Was missing, manually placing the file there fixes the issue

Since QGIS 3.0 is EOL, I think we should just adjust the compatibility version and forget about it.
