#bitbake Can't use 'bitbake -g <image-name> -u taskdep #bitbake

keydi <krzysztof.dudziak@...>

Myself had to ask web search engine for usage of Task Dependency Explorer taskexp as I didn't succeed on search in Yocto materials.
Hence, the way I try to use taskexp might be not right.

In the fashion as I try to start Task Dependency Explorer it does not work.
Invocation completes with error in __init__.py  -> require_version figures out lack of Gtk namespace.
Which is build-area Gtk is missed? Image, distribution, yet another? 
Which way of fixing should I aim to resolve error?

  File "/mnt/..../meta/poky/bitbake/lib/bb/ui/taskexp.py", line 22, in <module>
    gi.require_version('Gtk', '3.0')
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 130, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gtk not available
