Quick script to test if your project is using any of the modules he unpublished:

  for module in $(curl -s https://gist.githubusercontent.com/azer/db27417ee84b5f34a6ea/raw/50ab7ef26dbde2d4ea52318a3590af78b2a21162/gistfile1.txt); do grep "\"$module\"" package.json; done

If any names appear you should replace them or force that specific version always (remove ~ or ^ before it). If nothing appears you're probably good.
