Completion error when using gi.repository

[Jeansen]

Problem summary

I've just started with python and Gtk. So I added the deoplete-jedi plugin and installed jedi.

Using the following code

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk

win = Gtk.Window()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()

I can successfully write Gtk. and get a long popupt. But when I write win. I get the following error:

## Expected

I would expect a long popup with all the available methods/properties for GtkWindow.

It is jedi error instead of deoplete-jedi.

You can disable the error by g:deoplete#sources#jedi#ignore_errors.

@Shougo Thanks for the quick reply. That's what I was looking for but was not sure if it might be of interest. Closing this then.

@Shougo I am sorry, but it seems it is not an jedi issue. I opened an issue on the jedi side (https://github.com/davidhalter/jedi/issues/1345#issuecomment-506629188), but so far it seems jedi works fine. Especially with the latest version. And after I tried, waht was suggested by the author of jedi in his last comment, I can see no errors. In vim, they still persist :( Could you check or give me a hint what I can do to provide better debugging information?

[Shougo]

OK. Jedi's fix is not merged in deoplete-jedi. Please wait.

[Shougo]

Fixed.

@Shougo Great, works like a charm now :-) Thank you!
