Answer 1

Looks like a connection problem. Are you behind a proxy or something?

EDIT: Or maybe pointed at a local host npm repo or proxy? (On port 8080)

Ok, without knowing more about your system it's hard to give a non-exploratory answer, but I'll do my best to flesh it out as more of a recommendation.

It looks like your npm client is attempting to hit localhost:8080 to pull the module rather than the correct internet endpoint. If you've not configured a local NPM repository or anything like that, run npm config list to see if there's anything set in there that is causing things to hit that endpoint (e.g. a configuration value). You should also check your npmrc file, your package.json, and your environmental variables to see if there are settings in there that are affecting things; it looks like npm is expecting a proxy.
