Please help how to run on mac M1 , Node 16

opencv installed with:
brew install opencv@4
brew link --force opencv@4

it maybe u require error
it should be const cv = require('@u4/opencv4nodejs');

[nashxena]

Same error even after const cv = require('@u4/opencv4nodejs');

[1009058470]

I give up this
maybe u should have a look at opencv.js in u code and then
using const cv = require('where is opencv.js') and use it as tutorial

do not forget to ignore opencv.js for u tools for build

Hi there, I am experiencing the same issue.

[PavelPolyakov]

yeah, have the same.

It's possible to run it with OPENCV4NODES_DEBUG_REQUIRE=1 for more debug output. It starts to fail here: https://github.com/UrielCh/opencv4nodejs/blob/master/lib/cvloader.js#L60 , because we do not have path env variable, but have PATH.

Even when I change process.env.path to process.env.PATH, then it still tries to require opencv4nodejs.node. IDK why it shall be there (or somewhere, since we try to use opencv from brew).
