问题
Recently, I installed opencv with the following command:
brew install opencv
I found opencv3 was installed in dir /usr/include and /usr/lib. But what I want is opencv2. How can install opencv2 with the brew command?
回答1:
The easiest way to find the answer is to use brew search to look for available packages. So, in your case:
brew search opencv
There you will see the package opencv@2 listed. So, you need:
brew install opencv@2

I can't give you a answer in context of using brew but I can assist you with a valuable resource that really helped me out when I was first started out with OpenCV that got me up and developing https://www.youtube.com/watch?v=U49CVY8yOxw
Install Xcode , Install C-Make
Download OpenCV source code https://github.com/opencv/opencv/releases/tag/3.1.0
- Build and install!
INSTRUCTIONS: Go inside OpenCV once downloaded create new folder called build. Next, open CMake GUI find the directory we just created " build " to build the binaries, Click configure, Select "Unix Makefiles" and use native default compilers. cd into out build directory in our OpenCV folder so something like this /Users/you/Desktop/openCvFolder/build and run the command "make" and go have a coffee! I hope this helps it helped me out when I first started experimenting a year ago with OpenCV
