x11 - ImportError:没有名为“kivy.core.window.window_x11”的模块
提问于 2017-08-06 15:47:22
当我尝试在我的kali linux操作系统上用python3.5运行任何kivy程序时。然后我得到了下面的错误。
计划：-
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.relativelayout import RelativeLayout
Builder.load_string('''
<hey>:
RelativeLayout:
Button:
text:"Hey"
''')
class hey(RelativeLayout):
pass
class helloApp(App):
def build(self):
return hey()
if __name__=="__main__":
helloApp().run()错误：-

在我的例子中，它是一个过时的kivy版本。我看到你也在运行python3。删除kivy后，我做了以下操作，解决了我的问题：
sudo add-apt-repository ppa:kivy-team/kivy
sudo apt-get update
sudo apt-get install python3-kivyStack Overflow用户

pip install git+https://github.com/kivy/kivy.git@master它对我来说就像一个护身符。

在Ubuntu 19.04上，我基本上遇到了同样的错误(错误消息略有不同)
...
[CRITICAL] [Window ] Unable to find any valuable Window provider. Please enable debug logging (e.g. add -d if running from the command line, or change the log level in the config) and re-run your app to identify potential causes
egl_rpi - ImportError: cannot import name 'bcm' from 'kivy.lib.vidcore_lite' (/usr/lib/python3/dist-packages/kivy/lib/vidcore_lite/__init__.py)

from kivy.lib.vidcore_lite import bcm, egl即使在尝试了这些答案中的建议后，错误仍然存在。即使使用来自Kivy website的“稳定”包也无济于事，我必须承认这有点令人失望。
对我来说起作用的是通过pip3安装Kivy包，但这也需要一些依赖：
# remove the old packages
sudo apt-get remove --purge *kivy*
# install some dependencies for the package build
sudo apt-get install libav-dev libsdl2-dev libavformat-dev libavdevice-dev
# Install the kivy modules with `pip3` (assuming pip3 is installed already)
sudo pip3 install ffpyplayer
sudo pip3 install kivy
sudo pip3 install kivy-examples可能还有更多的依赖项需要通过pip3安装，我碰巧已经安装了。
