Error upon run: GTK version not specified.

[WaterSibilantFalling]

upon running tarpon

python tarpon.py

this error is returned and the application bails out, crashes or s.t.

src/tarpon_app/application.py:7: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

  from gi.repository import Gtk, Gio

Traceback (most recent call last):

  File "tarpon.py", line 9, in <module>

    from tarpon_app.application import Application

  File "src/tarpon_app/application.py", line 9, in <module>

    import appdirs

ImportError: No module named appdirs

Ignore the 'no appdirs', I have installed the requirements. However, see the other issue I have opened.
