Because the programming language is selected when Python. So, we have to let Python know that OPENCV exists. Watch the installation information at this time.

There is such a sentence:

If you need Python to find the installed site-packages:  echo '/usr/local/lib/python2.7/site-packages ' > ~/library/ Python/2.7/lib/python/site-packages/homebrew.pth

So, let's just do what it says. In the terminal, enter:

echo '/usr/local/lib/python2.7/site-packages ' > ~/library/python/2.7/lib/python/site-packages/homebrew.pth

For a test. Enter Python in the terminal,

Then enter:

Import CV

Import Cv2

Suppose there is no problem. is installed successfully.
