ratcave : 'scipy.spatial.transform.rotation.Rotation' object has no attribute 'as_dcm'

I'm trying to create a project using ratcave for python. But when I import ratcave, I get the following error:

AttributeError: 'scipy.spatial.transform.rotation.Rotation' object has no attribute 'as_dcm'

and this is the full stacktrace:

AttributeError: 'scipy.spatial.transform._rotation.Rotation' object has no attribute 'as_dcm'. Did you mean: '_uniforms'?

This is my code:

import pyglet
import ratcave as rc


# Create Window
window = pyglet.window.Window()


pyglet.app.run()
