404 loading socket.io.js

[jbraun27]

I just cloned this, ran npm install and ionic serve... haven't had much time to look into it, but the console reports:
No response for http://localhost:8080/socket.io/socket.io.js found in cache. About to fetch from network...
from ws.js. and the console too. I tried "ionic state reset", I tried commenting out the line in www/index.html that attempts to load

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

and tried loading it manually, but that didn't work.
Any ideas?
