x11 - ImportError: No module named 'kivy.core.window.window_x11

问题

Currently I am trying to build an App that I wrote in Python and Kivy via buildozer. Whatever I am doing, I am running into problems with window_x11. Even if I comment all the windows related things out in the code or doing all the things described in this post.

Here is a part of the error generated:

x11 - ImportError: No module named 'kivy.core.window.window_x11'

Another strange aspect is that I am using Python-3.x, but it keeps on saying about python-2.7.

running cython ./kivy/core/window/window_x11.pyx
()

from kivy.utils import platform

from window_info cimport WindowInfoX11

Currently I am lost in what to do and I also don't know where to start to solve the problem.

回答1:

This is a bug introduced in Kivy master, which is fixed in python-for-android's master branch. You can probably work around it by setting p4a.branch = master in the buildozer.spec, or using an older version of Kivy than the master branch (ideally Kivy 1.10).
