Fails at "npm install"

[novocodev]

I am trying to run the demo

I have successfully run nix-shell in the syn root folder, I have logged out and back in and run nix-shell again.

When I run "nom install" I get the following errors, any ideas what I need to do to fix these?

[nix-shell:~/syn]$ npm install
