mac上安装opencv与python

1安装Homebrew（mac上的一款出色的包管理器）

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"  

2安装Python

 brew install python  

3添加science仓库

brew tap homebrew/science

4确保自己安装了Numpy，如果没有，执行下面的语句

pip install numpy 

5安装opencv

brew install opencv  

6配置Python和OpenCV

cd /Library/Python/2.7/site-packages  
ln -s /usr/local/Cellar/opencv/2.4.9/python2.7/site-packages/cv.py 
ln -s /usr/local/Cellar/opencv/2.4.9/python2.7/site-packages/cv2.so  

7当你完成上述步骤后，打开终端，输入“python”，然后输入：

import cv2  

若没有报错，就表明你安装成功了！
