QtCore.so出错（找不到图片）

Question

运行OS X 10.11.2

我目前正在尝试运行名为CompuCell3D的程序（网站：http://www.compucell3d.org/）

启动时，我收到以下消息

---- ---- ---- ---- ---- ---- ---- ---- 
Hello World. Python --version says:
---- ---- ---- ---- ---- ---- ---- ---- 
Python 2.7.10
---- ---- ---- ---- ---- ---- ---- ---- 

 Now starting CompuCell3D 3.7.4  in GUI mode:

Traceback (most recent call last):
  File "/Users/Saamic/Downloads/CC3D_3.7.4/player/compucell3d.pyw", line 47, in <module>

这里出了什么问题？
