web app install failure

[abcnorio]

Dear all,

vtracer/ webapp latest github version

$ cargo --version
cargo 1.88.0 (873a06493 2025-05-10)
$ wasm-pack --version
wasm-pack 0.13.1
$ npm --version
10.9.2

OS = debian bookworm

Trying to install the webapp with

$ npm run build

resulted in

[...]
  opensslErrorStack: [
    'error:03000086:digital envelope routines::initialization error',
    'error:0308010C:digital envelope routines::unsupported'
  ],
  library: 'digital envelope routines',
  reason: 'unsupported',
  code: 'ERR_OSSL_EVP_UNSUPPORTED'
}

and was solved with

$ export NODE_OPTIONS=--openssl-legacy-provider

but next run resulted in

$ npm run build

How to solve this?

Thanks!

I think we're stuck in node.js 16

[abcnorio]

Thx, ie.

npm install nodejs@16

is the proper call?
