Error: Cannot find module '@tryghost/pretty-cli' on ghost start

Hello guys, I have an issue, I was working on a theme on a local version of ghost and it went fine for a couple of weeks, as of yesterday I started getting this error on “ghost start” o “ghost run”. I tried to install this package globally, run npm install at the root of the ghost folder, re install ghost-cli, with no success. Can someone help me please?
