Issue with opencv4nodejs Installation and Execution

[maybeing]

Hi! I'm facing many errors while setting up opencv4nodejs in my project. These are the current ones:

Opencv4nodejs Installation: I used pnpm to install @u4/opencv4nodejs, which apparently completed successfully without any errors.

PS C:\Users\XXX\backend> pnpm list
Legend: production dependency, optional only, dev only

backend@1.0.0 C:\Users\XXX\backend

dependencies:
@u4/opencv-build 1.1.0
@u4/opencv4nodejs 7.1.0
node-gyp 10.2.0
PS C:\Users\XXX\backend>

OpenCV Installation: I also installed OpenCV using vcpkg, and it confirmed that OpenCV 4.8.0 was already installed.

PS C:\Users\XXX\backend> vcpkg install opencv
Computing installation plan...
The following packages are already installed:
    opencv[core,default-features]:x64-windows@4.8.0#1
opencv:x64-windows is already installed
Total install time: 1.03 ms
opencv provides CMake targets:

  # this is heuristically generated, and may not be correct
  find_package(OpenCV CONFIG REQUIRED)
  # note: 10 additional targets are not displayed.
  target_link_libraries(main PRIVATE opencv_ml opencv_dnn opencv_core opencv_flann)

Build: I believe I managed to build opencv:

I tried deleting node_modules and reinstalling everything a few times, but still haven't been able to make it work.

Would deeply appreciate any help!

I tryed with choco but not with vcpkg

I should add a github action to test that package manager, can you try with chocolatey intead of vcpkg ?

test in progress: https://github.com/UrielCh/npm-opencv-build/actions/runs/10416302201/job/28848279864

[UrielCh]

fixed in @u4/opencv-build@1.1.1

Switching to Chocolatey did work after just a few more adjusts, thank you!!

[UrielCh]

fixed in V7.1.1
