我正在遵循OpenCV 文档并出现了一些失败。我按照步骤 2 并运行./opencv.sh，但结果
//home/voo-doo/anaconda2/lib/libQtGui.so.4: undefined reference to `png_get_channels@PNG16_0'

>>> from cv2.cv import *
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cv2.cv
我无法从该文档中找到任何解决方案。
总的来说，我只需要安装openCV并通过python环境使用它。
问题：我该如何解决这个问题？
