1. Believe this would be related to Elixir.
2. Not sure if this is an NPM issue that needs to be reported there, or if this is strictly related to Laravel 5.4 Elixir implementation.
3. Could also be a simple fix I can perform.

I get the error when Laravel runs npm update after composer update as well when running npm update myself.
