为什么我的 python 程序每次使用 ursina 引擎时都会给我一个 filenotfound WinError 3？

Question

我最近安装了 Ursina 游戏引擎并开始使用它，但是当我编写一个基本程序时，它给了我一个与 ursina 中的一些内置程序相矛盾的回溯并以指向与 python 无关的音乐文件夹的 Filenotfound Winerror 3 结束，我仔细检查了 Ursina 是否安装正确，但事实并非如此，我检查了它指向的文件夹预期仅包含音乐。引擎的路径有问题吗？我希望你能回答我。无论如何，这是代码：

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()

错误信息：

由于您将脚本直接放在桌面上，因此您将其作为项目文件夹。因此，当您尝试加载模型时，ursina 将在桌面上搜索您的所有文件和文件夹以查找与该名称匹配的文件。

将您的脚本和相关资产移动到一个单独的文件夹中。
