为什么每次使用 ursina 引擎时，我的 python 程序都会给我一个 filenotfound WinError 3？

Question

I have installed the Ursina game engine recently and I am getting started with it, but as I write a basic program it gives me a traceback contradicting some built in programs in ursina and ending with a Filenotfound Winerror 3 pointing to a music folder which has nothing to do with python, I double checked if Ursina is installed properly but it was not the case, and I checkedthe folder it is pointing to which as expected contained only music. Is there a problem with the path of the engine? I hope you can answer me. Anyway here is the code:

from ursina import *           # this will import everything we need from ursina with just one line.

app = Ursina()

player = Entity(
    model = 'cube' ,           # finds a 3d model by name
    color = color.orange,
    scale_y = 2
    )

def update():                  # update gets automatically called by the engine.
    player.x += held_keys['d'] * .1
    player.x -= held_keys['a'] * .1


app.run()

The error message:

Answer 1

Since you put your script directly on the Desktop, you made that your project folder. So when you try to load a model, ursina will search all your files and folders on the desktop for a file matching that name.

Move your scripts and relevant assets into a separate folder.
