Still Getting Error while using the package

          build-opencv --help
          And build missing file with:

          PS: a 'npm link' may help

same issue

Please provide all the lines you tape to produce the error and your environment variables.

in your case try a build-opencv rebuild without the version argument.

and please define your OPENCV_BUILD_ROOT environment variable. (in your case this folder should stay empty)

When using ones own build of OpenCV. what would build-opencv rebuild do?

Can this issue be resolved without rebuilding OpenCV or is that command not rebuilding OpenCV, only rebuilding a node specific interpreter?

In the "original" repo, I was able to install OpenCV using chocolatey, then install the node package while disabling autobuild, pointing to the correct lib, includes and bin directories, and the node_modules\opencv4nodejs\build directory was filled

Do so, use the chocolate build, The project contains a special code for that purpose.

and this case is tested by github action just here:

https://github.com/UrielCh/opencv4nodejs/blob/master/.github/workflows/prebuild.yml

When I run build-opencv rebuild It is failing due to my not having Visual Studio installed. I do not want to install Visual Studio but more importantly, I presume it needs VS due to it rebuild OpenCV which I don't want to do as I already have a version installed. So I guess I go back to these two questions:

1. When using ones own build of OpenCV. what would build-opencv rebuild do?
2. Can this issue be resolved without rebuilding OpenCV or is that command not rebuilding OpenCV, only rebuilding a node specific interpreter?

@UrielCh Any news? Things have gone a bit quiet around here

[UrielCh]

I'm currently working on a react native project that do not use openCV, I can not help you with that for now.

I have a familly to feed...

and yes you need visual studio installed to make it works.
