Issues with official docker image

[rstoye]

Hey there,

I'm trying to get a nestjs service of mine production ready and I'm struggling with the deployment process when using docker. Even with the official docker image I can't get the application to run.

I have provided an example project that anyone can clone and try for themself https://github.com/rstoye/opencv-troubleshoot-2. Just follow the readme of that repo to recreate the error.

The issue is that after installing the npm packages, linking the globally installed @u4/opencv4nodejs module and building the project, I get the following error upon running the build:

Error: Cannot find module '/usr/local/lib/node_modules/@u4/opencv4nodejs/build/Release/opencv4nodejs'
Require stack:

    '/usr/src/app/app.controller.js',
    '/usr/src/app/app.module.js',
    '/usr/src/app/main.js'
  ]
}

The error makes sense in that there certainly is no build folder under /usr/local/lib/node_modules/@u4/opencv4nodejs/. Why the path for the module wants to access a build/Release directory is beyond me. All I do in my source code is importing like so import * as openCv from '@u4/opencv4nodejs';

Any help on this matter would be greatly appreciated.
