What does `fail' mean here? Does it give an error message? The only ways
hash can fail are if it doesn't find the given name in $PATH or if the
given name, while found in $PATH, is not an executable file.

What is that expected to do? It certainly won't put `npm' into the hash
table. You probably want `hash -p /usr/bin/npm npm' instead.
