Python：导入OpenCV时出错

Question

我用自制软件安装了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 

如何解决此问题？

Answer 1

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

^的libpng尚未加载由于某种原因

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

^highgui试图加载它。

Reason: Incompatible library version 

^libopencv_highgui看起来需要至少版本34.0.0的libpng，而你的版本是33.0.0。我希望更新libpng应该可以做到。
