Description

Hi Everyone,

I am getting the the error ERR_DLOPEN_FAILED while trying to import opencv4nodejs with typescript.

The import statement I am using is this:

import * as cv from 'opencv4nodejs';

The error trace:

2024-06-05T11:54:06.190Z ERROR @wdio/config:ConfigParser: Failed loading configuration file: file:///D:/MSTeams%20Repos/BIM/MSTeamsAppTestingWDIO/wdio.electr

}

I have installed opencv, set the environment variables and disabled autobuild. The package successfully installs, but I get this error.

Research direction

Start by reproducing the Windows TypeScript import and inspect lib/cv.js, lib/opencv4nodejs.js, and the native build/Release path shown in the trace. Determine why the compiled addon cannot load despite installation, then verify that importing opencv4nodejs succeeds in the reported setup.
