Hi, I am trying to run the example code from the install Kivy. The following is the error I receive back. Any help would be great. I have tried looking at previous enquiries about similar problems, but nothing suggested on them has worked so far.

Code that I am trying to run:

import kivy
kivy.require('1.10.0') # replace with your current kivy version !

from kivy.app import App
from kivy.uix.label import Label


class MyApp(App):

    def build(self):
        return Label(text='Hello world')


if __name__ == '__main__':
    MyApp().run()

推荐答案

我遇到了同样的问题.我首先通过Kivy及其依赖项解决了它.

I had the same problem. I solved it by first Kivy and its dependencies.

python -m pip uninstall kivy

python -m pip uninstall kivy.deps.sdl2

python -m pip uninstall kivy.deps.glew

python -m pip uninstall kivy.deps.gstreamer

python -m pip uninstall image

现在重新安装除gstreamer之外的所有内容.

Now reinstalling everything except gstreamer.

python -m pip install --upgrade pip wheel setuptools

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew --extra-index-url https://kivy.org/downloads/packages/simple/

python -m pip install kivy

它解决了错误.归功于 Ben R的答案.
