Update: Since the --prefix option exists, I now vote for @coudy's answer to this question. Original answer below:

No, npm will always install in the current directory or, with -g, in the system wide node_modules. You can kind of accomplish this with a subshell though, which won't affect your current directory:

(cd some_project && npm install)

The parentheses makes it run in a subshell.
