python 导入 cv2 时出现 importError

Question

我已经使用 brew 安装了 opencv3，但是在执行 import cv2

时面临 importError

>>> 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/opt/libpng/lib/libpng16.16.dylib

  Referenced from: /usr/local/Cellar/opencv/2.4.12_2/lib/libopencv_highgui.2.4.dylib
  Reason: Incompatible library version: libopencv_highgui.2.4.dylib requires version 37.0.0 or later, but libpng16.16.dylib provides version 35.0.0

有人可以帮忙吗？
