Mopidy Fails on OSX 10.12.6 & 10.13.4

After installing the latest Sierra and High-Sierra security updates and running brew update I get

$ mopidy

ERROR: A GObject Python package was not found.

Mopidy requires GStreamer to work. GStreamer is a C library with a
number of dependencies itself, and cannot be installed with the regular
Python tools like pip.

Please see for
instructions on how to install the required dependencies.

I’ve completely removed homebrew and all formulas, and re-tapped and re-installed, and still get this error. suggestions?

running the latest gstreamer and gst plugins

$ brew info gstreamer
gstreamer: stable 1.14.0 (bottled), HEAD
Development framework for multimedia applications
/usr/local/Cellar/gstreamer/1.14.0_1 (415 files, 21.5MB) *
  Poured from bottle on 2018-04-01 at 17:50:07
==> Dependencies
Build: gobject-introspection ✔, pkg-config ✔
Required: gettext ✔, glib ✔, bison ✔
==> Options
	Install HEAD version
==> Caveats
Consider also installing gst-plugins-base and gst-plugins-good.

The gst-plugins-* packages contain gstreamer-video-1.0, gstreamer-audio-1.0,
and other components needed by most gstreamer applications.
