python - 使用 opencv-2.4.2 安装 pyopencv 2.1.0 时遇到错误

Question

我在安装 pyopencv 2.1.0 和 opencv-2.4.2 时遇到了一些错误，我的 python 版本是 2.7.3，我的操作系统是 OS X Mountain Lion，

下面是过程信息，我发现有一些错误显示'Mat'类被重新定义了，但我不知道如何解决，有没有 friend 能帮帮我？谢谢!

根据 pyopencv 的 Issue 47，OpenCV 2.3.1 或更高版本似乎与它不兼容。

考虑尝试使用 cv2.so 而不是 pyopencv。

它在我的 Mountain Lion 上运行良好。请务必制作本说明中描述的一些符号链接(symbolic link)。
