npm error required vs actual version?

I got a npm error installing express, what does this mean? I think it means I have to uninstall node and reinstall it? Or upgrade it perhaps. Can't figure out what I'm supposed to do and I'm reluctant to start screwing with it for fear of corrupting something.

Looks like a goof-up on the Express maintainer's part. He's letting Express 3.0.0 beta install on Node 0.4.x installs, but is requiring a library that will only install on 0.5.x and higher.

Try npm install [email protected] to get the latest release version (3.0 is still in beta) which is guaranteed to work on Node 0.4.x, or upgrade to the latest version of Node.js (now 0.8.1, I believe).
