安装opencv在MacOS上

标签：python   opencv   

1. 使用brew安装opencv

brew tap homebrew/science

brew install opencv

ls /Users/mac/Library/Python/2.7/lib/python/site-packages

mkdir -p /Users/mac/Library/Python/2.7/lib/python/site-packages

sudo mkdir -p /Users/mac/Library/Python/2.7/lib/python/site-packages

echo ‘import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")‘ >> /Users/mac/Library/Python/2.7/lib/python/site-packages/homebrew.pth

2. 查找到安装opencv库文件位置：

/usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv.py

/usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv2.so

3. 加入环境变量：

export PYTHONPATH=/usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/:$PYTHONPATH

4. 如果import cv2是出现ImportError: numpy.core.multiarray failed to import 请更新numpy库。

sudo pip install numpy --upgrade --ignore-installed
