No module named whiteboard.web_ui

[Florian Berger]

I installed WhiteboardPlugin on a Trac 1.2.5 install using Python 2.7.18 . I built an .egg, uploaded it into plugins/, and manually set

[components]
whiteboard.* = enabled

The plugin does not show up on the plugins page at /admin/general/plugin .

In the log, there are these messages:

Trac[loader] DEBUG: Adding plugin "whiteboard 0.1.0-trac0.12dev" from "<redacted>/plugins/whiteboard-0.1.0_trac0.12dev-py2.7.egg"
Trac[loader] DEBUG: Loading plugin "whiteboard.web_ui" from "<redacted>/plugins/whiteboard-0.1.0_trac0.12dev-py2.7.egg"
Trac[loader] ERROR: Skipping "whiteboard.web_ui = whiteboard.web_ui": ImportError: No module named whiteboard.web_ui

The web_ui module is clearly present in the .egg:

$ unzip -t plugins/whiteboard-0.1.0_trac0.12dev-py2.7.egg

    testing: whiteboard/htdocs/js/jquery.equalheights.js   OK
    testing: whiteboard/htdocs/js/whiteboard.js   OK
    testing: whiteboard/templates/whiteboard.html   OK

How do I make Trac find the module, and get the plugin working?

The problem had already been reported in February 2019 on trac-users here: ​Kanban / Whiteboard options , but did not receive any reply back then.

In 18619:

WhiteboardPlugin: add missing whiteboard/__init__.py (refs #14313)

Confirmed fix, the plugin is now usable with Trac 1.2.5 . Thank you.
