Python Kivy sdl2-运行时错误：b'；无法初始化EGL

我尝试使用OpenGL 1.1在Windows 7上运行以下示例脚本：

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()

我收到以下错误

我使用了用户环境变量KIVY_GL_BACKEND和值angle_sdl2

你知道我应该纠正什么并取得成功吗？

如果你用pip安装了kivy，试着这样做

现在重新安装除gstreamer之外的所有程序

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

这是从

您可以在安装步骤之后使用conda（我个人更喜欢这样）

不幸的是，为了正常工作，需要安装OpenGL 2+。否则，我不知道任何其他方法可以成功使用Kivy框架。关于你在Windows上更新到OpenGL 2+时遇到问题吗？目前我有一个足够旧的图形卡，可以通过驱动程序更新来支持OpenGL 2+。你知道有没有其他方法可以将我的OpenGL引擎从1.1升级到2+？那对我有很大帮助！谢谢你的帮助！不幸的是，为了获得OpenGL 2+，我无法通过“英特尔驱动程序与支持助手”或“英特尔82865G图形控制器驱动程序助推器”找到任何最新更新。再次问候。

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

conda install -c evindunn pygame
conda install -c conda-forge kivy
