Installing Solid server with

sudo npm install -g solid-server

results following errors:

Inizia riproducendo il problema segnalato di sudo npm install -g solid-server sulle versioni indicate di Ubuntu e Node, quindi esamina il passaggio postinstall di spawn-sync@1.0.15 e il relativo punto di ingresso postinstall mancante. Il lavoro è completo quando l’installazione globale termina senza l’errore Cannot find module né errori del ciclo di vita postinstall.
