Hi Ryan! Everything runs/compiles until I try starting the server -- not sure what is wrong.
npm run server fails for me with the following errors:

ncastello:~/work/git/rabbitbird-es2015-kit $ npm run server
[email protected] server /ncastello/git/rabbitbird-es2015-kit
http-server ./

npm ERR! Failed at the [email protected] server script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
