Panda3d 'Hello World' 示例中的导入错误

Question

我刚在我的Mac上安装了Panda3d，这是一个3D的Python游戏引擎。但是当我尝试运行“你好，世界”的示例时，

ppython helloworld.py

我遇到了一个问题：

Traceback (most recent call last):
  File "helloworld.py", line 1, in <module>
    from direct.showbase.ShoHewBase import ShowBase
  File "dstroot/pythoncode/Developer/Panda3D/lib/direct/showbase/ShowBase.py", line 10, in <module>
  File "/Developer/Panda3D/lib/pandac/PandaModules.py", line 8, in <module>
    from libpandaModules import *
  File "/Developer/Panda3D/lib/pandac/libpandaModules.py", line 2, in <module>
    Dtool_PreloadDLL("libpanda")
  File "/Developer/Panda3D/lib/pandac/extension_native_helpers.py", line 79, in Dtool_PreloadDLL
    imp.load_dynamic(module, pathname)
ImportError: dlopen(/Developer/Panda3D/lib/libpanda.dylib, 2): Library not loaded: @executable_path/../Frameworks/Cg.framework/Cg
  Referenced from: /Developer/Panda3D/lib/libpanda.dylib
  Reason: image not found

我猜我的引擎安装可能出错了，缺少了一些部分，但我不太确定该怎么解决这个问题。非常感谢任何帮助。谢谢。

根据Panda3D的入门指南中的“故障排除”部分，你可能需要安装Nvidia Cg工具包。
