`Hello, I have installed OpenCV on the Raspberry a couple of times. However, since everything is constantly evolving (OS, libraries, etc...). This time I am getting the following error:
-- Installing: /usr/local/lib/python2.7/dist-packages/cv2/python-2.7/cv2.so
CMake Error at modules/python2/cmake_install.cmake:61 (file):

I tried the following script:

I expected the library to be compiled correctly, however, this is what the console shows:

Any help would be highly appreciated. I will backup and upload the image after compiling for the mental health of many people.
I tried many things and solved the problem. The image of Raspbian Stretch + OpenCV 4 can be found here:
