If you haven't already set your NPM author info, now you should:
npm set init.author.name "Your Name"
npm set init.author.email "you@example.com"
npm set init.author.url "http://yourblog.com"
npm adduser
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
