It seems like there could have been two potential issues here. One is that the npm server may have had some issues at the time, you might want to try again now and see if you get the same error. The same question was asked in our Support forums (may even have been asked by you :) ) and another user said that trying again later fixed the issue:

Another issue is that you may be behind a proxy and can't connect to the npm server. You can set the proxy location using this command:
npm config set proxy http://url:port
Or if the proxy is authenticated:
npm config set proxy http://user:pass#url:port
