Cannot install in Loki

[ghost]

I added the repository as usual, and installed but it doesn't launch. I tried from the .zip code and gives me this error:

./scripts/elementaryplus-installer.py:24: 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, Gdk, Gio, Notify
Traceback (most recent call last):
  File "./scripts/elementaryplus-installer.py", line 24, in <module>
    from gi.repository import Gtk, Gdk, Gio, Notify
ImportError: cannot import name Notify

ImportError: cannot import name Notify Make sure you have installed the latest version of the python-gi and/or the python3-gi package.
