npm postinstall failed in windows

[spiritonly]

while windows do not have cp command, so "cp -n %s %s" failed when I execute "npm install".

changing to cp -u works
there are some modules related to angular that I needed to add manually with npm, and together with the change mentioned in an earlier post (changing bcrypt to bcrypt-nodejs) I was also able to get it up and running on Windows 8.1. Thank you pilwon!

I don't understand how changing to cp -u works when the copy command on windows is called copy (not cp).
