Question

当我尝试在我的kali linux操作系统中使用python 3.5运行任何kivy程序时。然后我得到以下错误。

程序： -

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： -

当我在之前的kali linux操作系统中安装kivy时，它曾经工作正常，但由于某些原因我再次安装kali并再次使用kivy，但这次我无法使其工作。

Answer 1

在我的情况下，这是一个过时的kivy版本。我看到你也在运行python3。删除kivy后，我做了以下解决了我的问题：

 sudo add-apt-repository ppa:kivy-team/kivy
 sudo apt-get update
 sudo apt-get install python3-kivy

Answer 2

在Ubuntu 19.04上，我基本上遇到了相同的错误（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)
  File "/usr/lib/python3/dist-packages/kivy/core/__init__.py", line 63, in core_select_lib
    fromlist=[modulename], level=0)
  File "/usr/lib/python3/dist-packages/kivy/core/window/window_egl_rpi.py", line 12, in <module>
    from kivy.lib.vidcore_lite import bcm, egl

即使尝试了这些答案中的建议，错误仍然存在。即使使用Kivy website中的“稳定”程序包也无济于事，我必须承认这有点令人失望。

对我有用的是通过pip3安装Kivy软件包，但这还需要一些依赖项：

# 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

我刚安装了pip3，可能需要安装更多依赖项。

Answer 3

pip install git+https://github.com/kivy/kivy.git@master

它对我来说就像一种魅力。

Answer 4

在Ubuntu 18.04.1。上运行我的第一个python3-kivy（v1.11.1）应用程序时遇到类似的情况。

以下是我的错误日志：

[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'

[CRITICAL] [App         ] Unable to get a Window, abort.`

对我有用的解决方案：

尝试安装python3-sdl2。 sudo apt-get install python3-sdl2并重新运行您的应用程序。

额外：设置python3-kivy并非一帆风顺。因此，在运行我的第一个应用程序之前，我将提出完整的安装步骤。希望它可以帮助某人：

# Install the dependencies
sudo apt-get install python3-setuptools libsdl2-dev libavformat-dev libavdevice-dev python3-sdl2

# Install python3-kivy via ppa. Pip install didn't work for me.
sudo add-apt-repository ppa:kivy-team/kivy
sudo apt-get update
sudo apt-get install python3-kivy

# Install ffpyplayer
python3 -m pip install ffpyplayer

# Run the app
python3 main.py

x11 - ImportError：没有名为＆＃39; kivy.core.window.window_x11＆＃39;
