I am using Debian Linux, and I have the package python3-gi installed from Synaptic, and this works fine if I use my Python 3.4 interpreter. But, when I run a Gtk+3 program using 3.5, it gets stuck at the from gi.repository import Gtk line, saying there's no module named Gtk. Additionally, I don't think that pip works for Python 3.5 on my computer, although I'm not sure. I just know that pip install PyGObject doesn't work. Finally, when I try to use Pycharm's specific package installer (Settings/Project Interpreter), Pycharm tells me that I don't have Python packaging tools installed (and it fails to install them when I click on the prompt it gives).
I have a 64 bit computer, Python 3.5 is installed to /usr/local/bin/ and Python 3.4 is installed to /usr/bin/.
You cannot use pip, you would have to download pygobject and build it from source yourself. https://download.gnome.org/sources/pygobject/
This is how I got Python 3.6 up and running with GStreamer bindings etc. on my Mac OS Sierra.
Follow from Step 1 if you have already installed Gstreamer and its plugins and you need to bind it to your python interpreter for development.
0a- Install gstreamer from their website ...normally and then
0b- brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-libav
1- brew install gst-python --with-python3
Note however that the 'gtk' for some reason doesn't come pre-bundled so we go to step 2.
2- brew install gtk+3
And that's it, easy as ABC...
Attached is a test python code to make sure you got everything right [OPTIONAL]
import gi, time, sys gi.require_version('Gst', '1.0') gi.require_version('GstBase', '1.0') gi.require_version('Gtk', '3.0') from gi.repository import GObject, Gst, GstBase, Gtk, GObject class Main: def __init__(self): Gst.init(None) self.pipeline = Gst.Pipeline() self.audiotestsrc = Gst.ElementFactory.make('audiotestsrc', 'audio') self.pipeline.add(self.audiotestsrc) self.sink = Gst.ElementFactory.make('autoaudiosink', 'sink') self.pipeline.add(self.sink) self.audiotestsrc.link(self.sink) self.pipeline.set_state(Gst.State.PLAYING) time.sleep(3) self.pipeline.set_state(Gst.State.PAUSED) self.pipeline.set_state(Gst.State.READY) self.pipeline.set_state(Gst.State.NULL) sys.exit(0) start = Main() Gtk.main()
Hope er'thing works out, c ya!!
