Salabim 不在 python 3.9 上运行

Question

I am trying to run the package salabim but I get a very weird error. I am currently using python 3.9 on a MacBook Pro running Big Sur 11.4

This is the sample code I am using

import salabim as sim


class Car(sim.Component):
    def process(self):
        while True:
            yield self.hold(1)


env = sim.Environment(trace=True)
Car()
env.run(till=5)

and this is the error

username@My-MacBook-Pro ~ % /usr/local/bin/python3 /Users/username/Desktop/Car.py
Traceback (most recent call last):
  File "/Users/username/Desktop/Car.py", line 11, in <module>
    env = sim.Environment()
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/salabim/salabim.py", line 4662, in __init__
    self.view = _AnimateIntro()
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/salabim/salabim.py", line 4434, in __init__
    self.setup(**kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/salabim/salabim.py", line 18276, in setup
    self.model_lights_pname = gl.GL_LIGHT_MODEL_AMBIENT
AttributeError: 'NoneType' object has no attribute 'GL_LIGHT_MODEL_AMBIENT'

This was a bug in version 21.1.1, which is corrected now. Please reinstall salabim. May I suggest subscribing to the salabim Google user group (see www.salabim.org )
