Python Config.prc文件必须通过load display或aux display至少命名一个有效的panda display库。错误

我正在使用panda3d，在代码中遇到了一个bug。我似乎找不到什么地方不对劲。 这是：

/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/panda3d/etc/Confauto.prc

:util: Reading /Users/Munish/Desktop/python/pygame_games/Config.prc

Your Config.prc file must name at least one valid panda display
library via load-display or aux-display.

这是我的Config.prc：

 window-width 1280 720

win-size 1280 720

我做错了什么？提前感谢您。

希望这能奏效：

3d.py：

来自panda3d.core导入加载文件
从panda3d.core导入ConfigPageManager
从direct.showbase.showbase导入showbase
打印（ConfigPageManager.getGlobalPtr（））
#资本化很重要。
loadPrcFile（'config.prc'）
类别MyGame（ShowBase）：
定义初始化（自）：
超级（）。\uuuu初始化\uuuuu（自）
game=MyGame（）
打印（基本）
game.run（）

config.prc:

 window-width 1280 720

win-size 1280 720

---

有人在吗？在你的prc文件中试试这个：win size 1280 720它仍然不起作用
