Finished all install setup steps (I believe)

firebase serve --only functions,hosting

=== Serving from '/Users/stephenfluin/workspace/fidget-spinner'...

i  functions: Preparing to emulate HTTPS functions. Support for other event types coming soon.
Warning: You're using Node.js v7.1.0 but Google Cloud Functions only supports v6.11.1.
i  hosting: Serving hosting files from: dist

Server#addProtoService is deprecated. Use addService instead
⚠  functions: Failed to load functions source code. Ensure that you have the latest SDK by running npm i --save firebase-functions inside the functions directory. Please note that emulation of custom config values are not supported yet. Run firebase serve --only hosting to only serve hosting files.

I had this same issue, and I think this may be related to #5. When I changed the line indicated in valueExists() return as explained in #5 I was able to get past this point.
