Node.js npm install module error

Here is my node and npm version: node -v v0.4.11 npm -v 1.0.27

When I tried to install a module for example express, I get the following error:

[root@localhost npm]# npm install express

Looks like your auth is set to something that doesn't work. Not clear how that happened -- perhaps check your /home/kelvin/.npmrc for a stray config? Shooting in the dark a bit. I would try npm mailing list if you don't find something in the rc.

isaacs: "The master branch from git is often unstable. This is fixed in HEAD already."

Solved after git pull, and make install.
