Manim: Error after installing manim

[AliNear]

I installed all manim & dependecies, but when I ran python -m manim example_scenes.py OpeningManimExample, I got the following error:
Traceback (most recent call last): File "c:\users\jm\anaconda3\lib\runpy.py", line 194, in _run_module_as_main return _run_code(code, main_globals, None, File "c:\users\jm\anaconda3\lib\runpy.py", line 87, in _run_code exec(code, run_globals) File "C:\Users\jm\Documents\work\manim_new\manim\manim.py", line 5, in <module> manimlib.main() File "C:\Users\jm\Documents\work\manim_new\manim\manimlib\__init__.py", line 9, in main scenes = manimlib.extract_scene.main(config) File "C:\Users\jm\Documents\work\manim_new\manim\manimlib\extract_scene.py", line 113, in main scenes = get_scenes_to_render(all_scene_classes, scene_config, config) File "C:\Users\jm\Documents\work\manim_new\manim\manimlib\extract_scene.py", line 74, in get_scenes_to_render scene = scene_class(**scene_config) File "C:\Users\jm\Documents\work\manim_new\manim\manimlib\scene\scene.py", line 44, in __init__ self.window = Window(self, **self.window_config) File "C:\Users\jm\Documents\work\manim_new\manim\manimlib\window.py", line 19, in __init__ super().__init__(**kwargs) File "C:\Users\jm\Envs\manim.new\lib\site-packages\moderngl_window\context\pyglet\window.py", line 51, in __init__ self._window = PygletWrapper( File "C:\Users\jm\Envs\manim.new\lib\site-packages\pyglet\window\win32\__init__.py", line 134, in __init__ super(Win32Window, self).__init__(*args, **kwargs) File "C:\Users\jm\Envs\manim.new\lib\site-packages\pyglet\window\__init__.py", line 603, in __init__ config = screen.get_best_config(config) File "C:\Users\jm\Envs\manim.new\lib\site-packages\pyglet\canvas\base.py", line 194, in get_best_config raise window.NoSuchConfigException() pyglet.window.NoSuchConfigException.
Any advice? And thank you

@TonyCrane Thanks a lot. I had the same problem. And your method is really useful!

For others (on Windows?) who have seen the above error and still have issues, I had to:
1) Install miktek to get rid of the File Not Found error.
2) And change this line:
https://github.com/3b1b/manim/blob/fe85d4e02f6935c49fb0b88eebbd492dfff2d324/manimlib/animation/creation.py#L136
to this:

            self.lag_ratio = min(4.0 / max(0.1, length), 0.2)

to get rid of the ZeroDivisionError: float division by zero error.
