This should solve the issue.

The problem that I was facing had something to do with the opencv4nodejs autobuild.

I was able to solve this by manually building opencv4nodejs.

"opencv4nodejs": { "disableAutoBuild": "1", "OPENCV_INCLUDE_DIR": "C:\\opencv\\build\\include", "OPENCV_LIB_DIR": "C:\\opencv\\build\\x64\\vc15\\lib", "OPENCV_BIN_DIR": "C:\\opencv\\build\\x64\\vc14\\bin" },

"scripts": { "install": "build-opencv --incDir C:\\opencv\\build\\include --libDir C:\\opencv\\build\\x64\\vc15\\lib --binDir C:\\opencv\\build\\x64\\vc15\\bin --nobuild rebuild" }

Replace each path in the lines above with your own respective path to opencv and add them to your package.json file,
Then run, npm run install to build opencv4nodejs. After a successful build you can then run your application.

When I try to do that I just get

'build-opencv' is not recognized as an internal or external command

[UrielCh]

try using npx
npx build-opencv --help

and use @u4/opencv4nodejs

try using npx npx build-opencv --help

and use @u4/opencv4nodejs

Thanks. I did switch over to @u4/opencv4nodejs. It does work better, I still have a problem when it comes to getting it to work in Electron though. I submitted an issue about it to @u4/opencv4nodejs

[UrielCh]

I do not use electron, please refer to the u4 election sample.

I tried and it gives this err;
I also tried with sudo and its still same
