Cannot run simple HelloWorld node.js script

I have just installed node.js on my ubuntu laptop.

I followed the instructions found here: http://davidtsadler.com/archives/2012/05/06/installing-node-js-on-ubuntu/#application and installed from the git repository

Installed with no errors, but when I ran the server.js sample application program nothing happened.

Worse still, I tried to run a ver basic hello world script called hello.js

console.log("hello world");

When I type : node hello.js

nothing happens, there is no error message, nothing is written to the console window.

IS there any known issues with node on ubuntu?

thanks

EDIT

just noticed in terminal if I type:

node console.log("hello world");

I get

$ node console.log("hi");

bash: syntax error near unexpected token `('
