Build errors trying to build onsets demo

[boxabirds]

What is the issue about?

• Bug
• Feature request
• Usage question
• Documentation
• Contributing / Development

What part(s) of Essentia.js is involved?

• essentia.js-core (vanilla algorithms)
• essentia.js-model (machine learning algorithms)
• essentia.js-plot (plotting utility module)
• essentia.js-extractor (typical algorithm combinations utility)

Description

yarn install inside demos/onsets fails. Is it because I don't have Python 2.7 installed? I'm happy to patch the scripts to support Python 3.x but the error is an inline command I can't find in source. And I'm also having difficulty building source so hopefully it's something else.

Steps to reproduce / Code snippets / Screenshots

yarn install

Output

(onsets) ➜  onsets git:(master) ✗ yarn install 
yarn install v1.22.19
