SyntaxError: Unexpected strict mode reserved word when trying to run under NixOS

Hi!

I'm trying to test your updated version of bower2nix (version 3.0.1) on my NixOS machine, and while it builds via default.nix, I cannot get it to run after installing the derivation. I get the following error when running bower2nix -v:

nix/store/ay1al3j3gvjfqdqp58kbn285qblcalir-nodejs-bower2nix-3.0.0/lib/node_modules/bower2nix/dist/bower2nix.js:26
let temp = require('promised-temp').track();

I am not very familiar with TypeScript (or JS for that part), so I think I need some help with debugging this. Any pointers? And thank you for your efforts to make bower2nix a useful tool with decent documentation!

Hi, thanks for testing! I think this is because I am running off nixos-unstable / nixos-16.03 and you're not. I have just tested on nixos-15.09 and got the same error. I will investigate ways of making it work with 15.09. I think it might be due to different nodejs version but not sure yet. Is it possible to develop from nixos-16.03?

Ah, yes, I should have mentioned that I only tried it under 15.09. It works when running against current master of nixpkgs. No need to get it working for 15.09!

Thank you and sorry for the noise!
