Make1:. modules/contrib/CMakeFiles/opencvcontrib.dir/all Error 2 make:. all Error 2 Then Nis Sarup says: $ brew unlink opencv $ brew uninstall opencv $ brew install opencv This eliminated the error: Segmentation fault: 11 when running the program with an ‘import cv2’. I am embarassed at asking this trivial question.

Hi, I followed you steps above and cv seems to be installed – if I now try ‘brew install cv’ I get ‘homebrew/science/opencv-2.4.13.2 already installed’. However when I run python or python3 and try ‘import cv’ I get the following error: Jonass-MacBook-Pro: Jonas$ python3 Error in sitecustomize; set PYTHONVERBOSE for traceback: KeyError: ‘PYTHONPATH’ Python 3.5.2 Anaconda 4.2.0 (x8664) (default, Jul 2 2016, 17:52:12) GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28) on darwin Type “help”, “copyright”, “credits” or “license” for more information.
