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)

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 ?

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

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.
