Could not find moment.js library

Hi,
I am trying to implement Line Chart with Time Scale. See http://www.chartjs.org/samples/latest/scales/time/line-point-data.html.

However, I am running into issue where chart.js library cannot find moment.js library. See following screenshot of Google Chrome's console:

I have included moment.js library in my project using bower but still no luck.

Any suggestion/workaround to resolve this issue?

Thanks.
