ImportError: cannot import name 'GraphicsView' from 'graphics'

[zhengyang007]

Hello，

Thanks for your great job, when I tried to run this procject (pythonocc-vericut), the error record in the Title will occur,
I have already installed the graphics (Version: 0.1) and graphics-py (Version: 5.0.1.post1)，and my python version is 3.8.

Would you like to tell me the specific version of the "graphics " that you used, and share the install manual with me?
P.S. I would appreciate it that if you can share the ".yml" of your environment.
