Working with demo/nodjs/node-webcam.js

[saeidn95]

I am not able to run "demo/nodjs/node-webcam.js"
I also tried "demo/nodjs/node-webcam.js /dev/video0"
I get the ""Error: Cannot find module 'node-webcam':

"node:internal/modules/cjs/loader:1146
throw err;
^

Node.js v20.12.1

some demos need additional requirements as i don't want to flag them as needed by core repo since they would only be used by that demo and not by core human library itself.
in that case, simply use npm install ... whatever is needed.

I did "npm install node-webcam", It came back with "Error: Cannot find module '@vladmandic/pilogger'"

I did "npm install --dev" the second time. I works now!

Thanks a lot!
