How do I build this (using e.g. `npm run build`)?

[ApproximateIdentity]

I tried installing a fresh node environment:

twn$ nodeenv --prebuilt nodeenv
 * Install node (15.5.1)... done.
twn$ source nodeenv/bin/activate
(nodeenv)twn$ npm install

added 380 packages, and audited 381 packages in 4s

4 vulnerabilities (3 low, 1 high)

To address all issues, run:
  npm audit fix

Run `npm audit` for details.
(nodeenv)twn$ npm install --global

added 1 package, and audited 3 packages in 472ms

found 0 vulnerabilities

Then I tried to run build:

(nodeenv)twn$ npm run build

> handtrackjs@0.0.13 build
> rollup -c

sh: 1: rollup: not found
npm ERR! code 127
npm ERR! path /home/twn/repos/github.com/victordibia/handtrack.js
npm ERR! command failed
npm ERR! command sh -c rollup -c

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/twn/.npm/_logs/2021-01-07T20_53_32_648Z-debug.log

Okay so I tried installing rollup:

(nodeenv)twn$ npm install rollup
npm WARN deprecated fsevents@2.1.3: "Please update to latest v2.3 or v2.2"

added 2 packages, and audited 383 packages in 1s

4 vulnerabilities (3 low, 1 high)

To address all issues, run:
  npm audit fix

Run `npm audit` for details.
(nodeenv)twn$ npm install --global rollup
npm WARN deprecated fsevents@2.1.3: "Please update to latest v2.3 or v2.2"

added 2 packages, and audited 3 packages in 509ms

found 0 vulnerabilities

Then I tried running build again:

(nodeenv)twn$ npm run build

> handtrackjs@0.0.13 build
> rollup -c

What am I missing here? I'm sure this is something basic and obvious for those a bit more experienced with node, but I'm a little lost. By the way, I'm running

• Debian 10
• node version 15.5.1 (as seen above)
• npm version 7.3.0

Thanks for any help! And thanks for the super interesting project!

Its been a while since I worked on this, don't have any immediate feedback. Back then, I used rollup.js for bundling up the model .

the same question

Got it, little modification in rollup.config.js should work Use rollup-plugin-terser instead of rollup-plugin-babel-minify as the latter one is archived, maybe something incompatible. And this will fix the wtf Banner problem. By the way, rollup-plugin-node-resolve is archived too, better change to @rollup/plugin-node-resolve.

the final code is like this:

// import minify from 'rollup-plugin-babel-minify';
// import resolve from 'rollup-plugin-node-resolve';
import {nodeResolve} from '@rollup/plugin-node-resolve';
import {terser} from 'rollup-plugin-terser';

// ..

plugins: [nodeResolve(), terser()]
