Plugin doesn't load

[johnwbryant]

Describe the bug
Plugin doesn't load.

To Reproduce
Steps to reproduce the behavior:

1. Open Plugin Manager
2. Find Kart plugin and attempt to install
3. Get error: Couldn't load plugin 'kart' due to an error when calling its classFactory() method, ModuleNotFoundError: No module named 'mock' (full error below)
4. Install from zip instead
5. Close & re-open QGIS
6. On QGIS start, same error

Expected behavior
I expected the plugin to install & open without error.

Version info (this is important!):

• Operating System (e.g. Windows 10, macOS): Ubuntu 20.04
• QGIS, Kart & Plugin details:
  • Kart v0.10.7
  • QGIS version: 3.22.1

Additional context

Hi John,

Where did your QGIS come from? UbuntuGIS? Built locally?

[volaya]

Should be fixed by 46a8aac

[johnwbryant]

Nice! Thanks @volaya, v1.01 installs without any issues.

@rcoup sorry for the late reply, maybe a moot point now, but my QGIS came from the QGIS Ubuntu repo here: https://qgis.org/ubuntu/
