Polymer build error while using polymerfire

Question

When trying to build using polymer fire, I'm getting this error, has anyone seen this before?

What does 'no resolver found' mean?

error: Promise rejection: Error: no resolver found for ../../../../bower_components/firebase/firebase.js

The import I have is

<link rel="import" href="../../bower_components/polymerfire/polymerfire.html">

The version of polymerfire I'm using is

"polymerfire": "firebase/polymerfire#^0.9.3",

Full error log:
