Give permission to npm

This looks like a permissions issue in your home directory. To reclaim ownership of the .npm directory execute

sudo chown -R whoami ~/.npm

How to install opencv in mac os 10.9
http://stackoverflow.com/questions/19707468/installing-opencv-2-4-2-on-mac-os-x-10-9-mavericks
----------------Approach 1---------------
I tried your problems and I think steps are as follow:
open terminal in mac
in the terminal, check you have cmake and ccmake. If not, please type "brew install cmake"
go to your downloaded opencv folder, make a new folder by typing "mkdir build", then "cd build"
in this build folder, check you have gcc and g++ installed.
