Installing opencv4nodejs under "C:\Program Files\some_dir" or similar will not work and will fail with: "fatal error C1083: Cannot open include file: 'opencv2/core.hpp'"!** Important note: node-gyp won't handle whitespaces properly, thus make sure, that the path to your project directory does not contain any whitespaces. If you are running into node-gyp specific issues have a look at known issues with node-gyp first. However, node-gyp requires you to have python installed. Native node modules are built via node-gyp, which already comes with npm by default.

The ultimate goal of this project is to provide a comprehensive collection of nodejs bindings to the API of OpenCV and the OpenCV-contrib modules. opencv4nodejs supports OpenCV 3 and OpenCV 4. Besides a synchronous API the package provides an asynchronous API, which allows you to build non-blocking and multithreaded computer vision tasks. It should take just a few seconds to complete execution.Opencv4nodejs allows you to use the native OpenCV library in nodejs. The final step here is to execute - sudo make install. After it’s done you should get an output like so. You can adjust the j option with respect to the hardware available. With all the eight cores ( j8 stands for eight cores here) chugging along, this step took ~8 minutes for me.

Next, we launch the make command - make -j8. The compilation took ~3 minutes for me and it should produce outputs like so. Now, before you run the above cmake command, activate the conda environment you created in an earlier step ( conda activate ) if you haven’t already. For these two arguments, you would want to first determine the paths and then supply them accordingly. Also, please pay attention to the following arguments - OPENCV_EXTRA_MODULES_PATH and PYTHON3_EXECUTABLE. D PYTHON3_EXECUTABLE =/Users/sayakpaul/miniforge3/envs/dev/bin/python3 \Īs per this issue comment, DCMAKE_SYSTEM_PROCESSOR, DCMAKE_OSX_ARCHITECTURES, DWITH_OPENJPEG, and DWITH_IPP are needed to be set during the compilation step.
