If you want to install it manually, it's here:

http://expat.sourceforge.net/

If you want to install it using MacPorts, run:

sudo port install expat

Other methods might include using Fink or Homebrew.

What did you do, exactly?

And how is npm installed?

Perhaps you need to inform npm where you have installed expat. (Usual environment variables to do that would be CPPFLAGS and LDFLAGS.)
