11 years ago It looks like opencv is not installed on your server. If you have Ubuntu, try sudo apt-get install opencv or sudo apt-get install libopencv-dev
Otherwise, try looking up in the OpenCV documentation how to install it for your own distribution. You do not need bea to install opencv-node --> it's a tool used to generate C++ files.

Hi,
I've always successfully installed opencv-node so far, but i just tried to move it to my production server. I get stuck at this point because he is missing some files. (i've tried to handle it with npm install opencv-node and also by install bea and cloning the repo manually) Here is the output when i try to build it manually :

Do you have an idea ?
