Tryton requires pygtkcompat, but OS doesn't provide it

[fmorato (Felipe Morato)]

I just tried the following on OpenSuse Tumbleweed with Gnome, and it doesn’t seem to have pygtkcompat.

$ pip install --user tryton

$ .local/bin/tryton

Tryton starts, but upon login in, I still get:

ModuleNotFoundError: No module named 'pygtkcompat'

According to Files · main · GNOME / pygobject · GitLab, it is still included in pygobject.

I did read through the other threads on the pygtkcompat, but regardless of maintainability, being supported or not, I can’t run Tryton either from source or by installing with pip.

Tryton 6.0 client requires pygtkcompat

I have installed Tryton 6.0 client via pip3 on a fresh Tumbleweed system and MATE desktop, Python 3.8.8 When attempting to connect to the demo server it crashes with: ModuleNotFoundError: No module named ‘pygtkcompat’ As this was an issue for Tryton 5.0 (https://discuss.tryton.org/t/why-does-tryton-still-needs-pygtkcompat-library/1608/13), I seem to remember that full Python3/GTK3 compatibility was planned for Tryton 5.2?

Why does Tryton still needs pygtkcompat library?

Stumbled over this while compiling Tryton 5 client. According to https://bugs.tryton.org/msg47158 it should have been removed, as this seems to be not needed/not supported anymore in python-gobject.

What is the solution?

First you should complaint to OpenSUSE to explicitly remove some standard features of a package (which is not only for backward compatibility).
Now tryton needs only pygtkcompat.generictreemodel (in tryton/gui/window/view_form/view/list.py).
So you could copy the generictreemodel.py in this folder and replace the line:

from pygtkcompat.generictreemodel import GenericTreeModel

by

from .generictreemodel import GenericTreeModel

..or just review the prior discussions on that, this should answer it.

@fmorato - why dont you just use the tryton-packages in Application:ERP:Tryton:6.0 ?
(OK, I have not announced its availability…but from the link on tryton.org one should get there)

[fmorato (Felipe Morato)]

Thanks for both answers. I can see from the OpenSuse Tryton repo that they are manually adding generictreemodel to the Tryton package.

Adding the repo for Tryton 6.0 and installing the Tryton package.

# zypper ar -f https://download.opensuse.org/repositories/Application:/ERP:/Tryton:/6.0/openSUSE_Tumbleweed Tryton
# zypper in tryton

It’s nice to have it installed as a system package ^^

On a side note, I guess reading the threads and no mention of the repo, I totally forgot about the repository links on the website.
