Ahh yes the following works to install it globally.

npm install -g puppeteer --unsafe-perm=true
npm install -g magepack --no-optional

Now i just need to work out why it hangs after Collecting modules for bundle "category"

[gwharton]

Yes, as it turns out I had xdebug enabled and my ide had actually dropped into a debug session without me noticing which was hanging the return of the webpage to magepack. You should try manually browsing to the url’s that you are passing to magepack. They need to work and return a good webpage without errors when accessed from the machine running magepack. Try wget/curl and inspect the source of the page you get back if you are in console only.
