导入错误：找不到框架/System/Library/Frameworks/OpenGL.framework

我正在尝试在新的macOs Big Sur上运行这个简单的健身房示例。

import gym
env = gym.make('CartPole-v0')
env.reset()
for _ in range(1000):
    env.render()
    env.step(env.action_space.sample()) # take a random action
env.close()

但是，我遇到了这个

Traceback (most recent call last):

ImportError: Can't find framework /System/Library/Frameworks/OpenGL.framework.

During handling of the above exception, another exception occurred:

    HINT: make sure you have OpenGL install. On Ubuntu, you can run 'apt-get install python-opengl'.
    If you're running on a server, you may need a virtual frame buffer; something like this should work:
    'xvfb-run -s "-screen 0 1400x900x24" python <your_script.py>'

我遵循了这个和这个讨论，但找不到可行的解决方案。有人可以帮忙吗？

附加信息

• macOS 大苏尔 11.0.1
• 蟒蛇 3.9.0
• PyOpenGL==3.1.5
• pyglet==1.5.11（运行后pip install pyglet==1.5.11显示Requirement already satisfied: pyglet==1.5.11 in /Library/Frameworks/...，但是，print(pyglet.version)在我的脚本中运行时，我得到了1.5.0）。1.5.11即使它已经安装，我该如何更改？
