描述

嗨，我正在尝试从安装Kivy运行示例代码。以下是我收到的错误。任何帮助都会很棒。我曾尝试查看有关类似问题的先前查询，但到目前为止，有关这些问题的建议均未奏效。

代码和日志

我尝试运行的代码：

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()

Answer 1

我有同样的问题。我首先通过Kivy及其依赖项解决了它。

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。

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。
