Cannot get goocanvas on Fedora 26 to work using pygobject

[Fred van Zwieten <fvzwieten gmail com>]

Hi,

I am trying to get goocanvas to work on Fedora 26 but I only get it to work with PyGTK, but not with pygobject.

Packages installed:
python3-gobject.x86_64 : Python 3 bindings for GObject Introspection
gobject-introspection.x86_64 : Introspection system for GObject-based libraries
pygoocanvas.x86_64 : GooCanvas python bindings

with pip and pip3 pgi is installed

>>> import gi
>>> gi.require_version('Gtk','3.0')
>>> from gi.repository import GooCanvas
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 879, in _find_spec
AttributeError: 'DynamicImporter' object has no attribute 'find_spec'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python3.6/site-packages/gi/importer.py", line 127, in find_module
    'introspection typelib not found' % namespace)
ImportError: cannot import name GooCanvas, introspection typelib not found

Same issue with both python2 and python3

Any ideas?
