Python：导入OpenCV时出错

Question

我用Homebrew安装了opencv。 我收到以下错误-

>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/cv2.so, 2): Library not loaded: /usr/local/lib/libpng16.16.dylib
  Referenced from: /usr/local/Cellar/opencv/2.4.11_1/lib/libopencv_highgui.2.4.dylib
  Reason: Incompatible library version: libopencv_highgui.2.4.dylib requires version 34.0.0 or later, but libpng16.16.dylib provides version 33.0.0

我该如何解决？

Answer 1

Library not loaded: /usr/local/lib/libpng16.16.dylib

^由于某种原因尚未加载libpng

Referenced from: /usr/local/Cellar/opencv/2.4.11_1/lib/libopencv_highgui.2.4.dylib

^ highgui尝试加载它。

Reason: Incompatible library version

^ libopencv_highgui似乎至少需要版本34.0.0的libpng ，而您拥有版本33.0.0。 我希望更新libpng应该可以解决问题。
