Cannot find module node_modules/opencv4nodejs/build/Release/opencv4nodejs

I am on windows 11 using Visual Studio Code 2022 to try and build.

Trying to run & build an express node.js app in Visual Studio 2022. I have installed the npm package opencv4nodejs and added the required opencv enviormental variables to my path. When I try to build the app I get this error
Error: Cannot find module 'C:\Users\Tom_R\source\repos\AberothNodeClient\AberothNodeClient\node_modules\opencv4nodejs\build\Release\opencv4nodejs'

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.
