We're closing this support issue as it has gone three days without activity. The npm CLI team itself does not provide support via this issue tracker, but we are happy when users help each other here. In our experience once a support issue goes dormant it's unlikely to get further activity. If you're still having problems, you may be better served by joining WeAllJS and asking your question in its #npm channel. The npm CLI team is all present there, but there are also lots of other folks who can help you too.
