Starting application using node works but not yarn or npm

There is probably an obvious answer to someone who is more familiar with NodeJS than me but:

When running an application which is using a node-gyp package, it runs without problems using node ./src/index.js

However running it using a very simple package.json start-script:

"scripts": {
    "start": "node ./src/index.js"
  }

in npm:

npm start

npm info it worked if it ends with ok
npm info using npm@6.9.0
npm info using node@v11.10.1
npm info lifecycle rosbag2@0.1.0~prestart: rosbag2@0.1.0
npm info lifecycle rosbag2@0.1.0~start: rosbag2@0.1.0

> rosbag2@0.1.0 start /Users/andreasklintberg/personal/xviz/examples/converters/rosbag2
> node ./src/index.js "./src/index.js"

internal/modules/cjs/loader.js:779
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

And similarly in yarn yarn start

yarn run v1.13.0

$ node ./src/index.js ./src/index.js -d ../../../data/rosbag2/rosbag2_2019_03_09-21_54_44 -o ../../xviz-data/rosbag2/rosbag2_2019_03_09-21_54_44/

I know the error is because a dynamic link/@rpath is messed up, and I was thinking it was because npm/yarn messes with the env variables or something, but running yarn env it seems everything is correct.

So I guess i'm wondering if anyone know what the difference is running it in native node and using npm/yarnscript to wrap the start? And why this difference messes up the @rpath/dynamic linking ?
