Question

这是众所周知的，很常见的问题。我尝试了所有找到的解决方案，但没有成功。我正在尝试使用kivy制作简单的python应用程序。运行下面的代码后，我得到了很多错误。代码：

import kivy
kivy.require('1.9.1')

import os
os.environ['KIVY_GL_BACKEND'] = 'angle_sdl2'

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

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

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

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

运行代码后：

PATH和PYTHONPATHS包含：

C:\Windows\System32;
C:\Python;
C:\Python\DLLs; 
C:\Python\Lib;
C:\Python\Scripts;
C:\Python\share\sdl2;
C:\Python\share\glew

在我开始调查之前，我已经看到了：

POP Window

我尝试过很少的口译员。 Python 3.5.2、3.6.1和3.7.2。错误是一样的。有任何想法吗？
