Stuck on start with patternlab twig-php engine

[guillorrr]

I am using Pattern Lab Node v6.1.0 on Ubuntu 20.01.6 LTS, with Node v18.20.2, and using the twig-php pattern engine.
I also tried with node 16 y 20.

I'm having trouble on the init start.

npm run start

> patternlab@1.0.0 start
> npm run serve


> patternlab@1.0.0 serve
> patternlab serve --config ./patternlab-config.json

⊙ patternlab → serve: Serving your files …
Pattern Lab Node v6.1.0
