Human Demos for NodeJS

[saeidn95]

I am referring to the instruction in (https://github.com/vladmandic/human/tree/main/demo/nodejs) for running the Human Demos for NodeJS.

I have tried (node demo/nodejs/node.js) from a terminal. However, I get the following error message. I wonder if it a version compatibility issue or something else. I am using v12.22.9 on Ubuntu 22.04.4 LTS

~/human/demo/nodejs/node.js:68
log.data('Image bytes:', buffer?.length, 'buffer:', buffer?.slice(0, 32));
^

SyntaxError: Unexpected token '.'

package.json does specify:

  "engines": {
    "node": ">=14.0.0"
  },

nodejs 12 was introduced in 2019-04-23 and had end-of-life in 2022-04-30 which is 2 years ago.

Thank you for the help.

I have upgrade Node.js to v20.12.1. Now I get the following error message complaining about not finding module '@vladmandic/pilogger' Do I have to download some additional modules?

node ./demo/nodejs/node.js
node:internal/modules/cjs/loader:1146
throw err;
^

  }

Node.js v20.12.1

to run demos, you need to install dependencies.
npm install

[saeidn95]

I ran "npm install" from the human folder I also ran "sudo npm install". Neither installed the vladmandic/pilogger' dependency I still get the Error: Cannot find module '@vladmandic/pilogger'

Do I have to clone the git repo with some options?

[saeidn95]

Update: I also tried rebuild the prohect by following the instruction (https://github.com/vladmandic/human/wiki/Build-Process)
npm install --dev # installs all project dependencies
npm run build
I still get the same error "Error: Cannot find module '@vladmandic/pilogger'"

Next I commented out const "log = require('@vladmandic/pilogger')" from node.js file. Next I get a new error "Error: Cannot find module '@tensorflow/tfjs-node'"

I tried to install with " npm install @vladmandic/human @tensorflow/tfjs"
as stated in (https://github.com/vladmandic/human/wiki/Install). This did not work either I still get the same error. Some how the dependencies do not get installed or something.

npm install @vladmandic/human @tensorflow/tfjs

[vladmandic]

git clone https://github.com/vladmandic/human human-test
cd human-test
npm install --dev

OMM! Great! it works now! I swear I followed the same steps before!
Thanks a lot. I can also build using "npm run build"
