Kivy 错误：[严重] [应用程序] 无法获取窗口，中止

我看到的针对这个 Kivy 错误的所有解决方案对我来说都不起作用。现在已经过去两周多了，但我所有的努力都白费了。我使用 python 3.6.4、kivy 1.10.1、pycharm 作为我的 IDE 和 Windows 10。这是错误代码和代码本身：

代码：

from kivy.core.window import Window
import os
os.environ['KIVY_GL_BACKEND'] = 'angel_sdl2'
from kivy.app import App
from kivy.uix.button import Button

# from kivy import Config
# Config.set('graphics', 'multisamples', '0')

class MyApp(App):
  def build(self):
     return Button(text='Hello world')


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

错误：

我的计算机使用的是 opengl 1.1，因为其他版本不兼容，所以我决定使用“angel sdl2”。谢谢

在配备 Intel GMA 965 和 Win10 的笔记本电脑上出现同样的问题

原因：显卡驱动过时，没有新版本。

解决方案 （为我工作):

1) 使用pal1000工具https://github.com/pal1000/save-legacy-intel-graphics

（更多信息位于https://community.khronos.org/t/i-have-opengl-3-1-but-kivy-says-that-i-have-only-1-1/103980/6)

2）安装依赖项，例如

python -m pip install --ignore-installed kivy.deps.sdl2 kivy.deps.glew

（并将系统变量“KIVY_GL_BACKEND”设置为“glew”，或者不设置 - 这是默认值；顺便说一句，安装 kivy.deps.angle 并设置“angle_sdl2”别帮忙我在这种情况下）

3）在python代码之前添加：

from kivy import Config
Config.set('graphics', 'multisamples', '0')

(from Kivy 未检测到 OpenGL 2.0)
