Opencv安装错误

Question

我用home-brew安装了opencv并在python中运行了命令import cv，这给出了以下错误。

我正在使用MAC OS 10.10。

问题是什么？

Jays-MacBook-Air:caffe jay$ brew install opencv
Warning: opencv-2.4.10.1 already installed
Jays-MacBook-Air:caffe jay$ python

>>> import cv
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named cv
>>> 

错误是什么？

我是否需要为opencv设置路径？

谢谢：）

Answer 1

第一步是查找cv2.so所在的位置 locate cv2.so。

我的电脑输出为/usr/local/lib/python2.7/site-packages/cv2.so。

然后，添加一行

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

在〜/ .bash_profile中让python找到库。
