ember firebase deploy -- events.js:85 -- throw er; // Unhandled 'error' event -- Error: spawn

I'm following the directions from http://ift.tt/1Kz4P76 to set up a new firebase hosted app. I get to the end of the instructions and the 'ember firebase deploy' command fails. Here are the steps I'm taking:

C:\workspace\npm install -g firebase-tools

C:\workspace\cd dashdash

C:\workspace\dashdash\firebase login

C:\workspace\dashdash\npm install --save-dev ember-cli-firebase-hosting

C:\workspace\dashdash\ember generate firebase-hosting

C:\workspace\dashdash\ember firebase deploy

It works fine up until the last step. Instead of getting a success message and the URL of my app, I get the following:

C:\workspace\dashdash>ember firebase deploy
version: 1.13.8
Built project successfully. Stored in "dist".
events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: spawn C:\workspace\dashdash\node_modules\ember-cli-firebase-hosting\node_modules\firebase-tools\bin\firebase ENOENT
    at exports._errnoException (util.js:746:11)
    at Process.ChildProcess._handle.onexit (child_process.js:1053:32)
    at child_process.js:1144:20
    at process._tickCallback (node.js:355:11)

I haven't changed the app in any way when I get to that step, and I can serve it successfully to http://localhost:4200/ and get the "Welcome to Ember" message.

I'm running Windows 7 Professional (SP1) and using Windows Power Shell (run as administrator) to give the commands. I've also tried in PHPStorm's terminal.

I'm just learning about Ember, so if I've left something out (I probably have,) let me know. I'm more than happy to gather any necessary information. Any help/advice will be much appreciated.

Thanks, Bret
