It worked when specifically installing opencv-build before-hand, but make sure neither opencv-build nor opencv4nodejs are actually defined in package.json dependencies,

So what I did is install them via postinstall as such:

"scripts": {
    "postinstall": "npm i opencv-build && npm i opencv4nodejs",

For this, I first had to install cmake in my case.

brew install cmake

BTW: It also took quite a while to install opencv-build - minutes of very intensive processing - according to the extra heat and sound emitted, and I thought it was stuck at first.

With this approach we can use opencv4nodejs but it's not listed as a dependency.
