Installation problems in QGIS master (3.11)

[andreasneumann]

When trying to install the SoLocator plugin in QGIS master (3.11) on Linux I get the following error message and the plugin can't load:

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

AttributeError: module 'solocator.core' has no attribute 'settings'

I could not replicate with a clear new profile.

[andreasneumann]

Strange - I just recompiled master again and started a new profile. Still the exact same error message like above in my ticket.

Some local issue with my machine?

@m-kuhn could you please test if you can install the SoLocator in recent master on your Linux machine?

[3nids]

Maybe it's a Python 3.6 vs 3.7 issue. I will look again at these imports if I can do differently

[3nids]

Someone else tested on a Linux machine with Python 3.8 without issue. Still waiting for another test with 3.6

[andreasneumann]

Ok - I will also test tonight on my home machine and report back.

[andreasneumann]

FYI - on the same machine (same Python) the SoLocator plugin also doesn't install in version 3.4.12 and also not in QGIS 3.8.3 (all self-compiled). Other Python plugins run fine and also an older version of SoLocator installed fine.

Should I test the older SoLocator version to see which one still installed ok?

[3nids]

I tried an alternative approach for import to avoid circular dependencies, and it apparently fails on Python 3.6. Will try to fix this.

[3nids]

fixed in dd2a839

[3nids]

released in 1.2.2 (should be available in QGIS within 15-60 minutes)

[andreasneumann]

Seems to work fine now on my Linux/Python 3.6 machine.

Thanks a lot!
