error installing npm@1.1.1 on Mac OS X Lion

Question

I am trying to get going with express framework on Mac OS X Lion. Having these issues:

npm not ok
It failed

Node version v0.6.1.

I looked around on the web and most of the answers are from node 0.4 days and they all just say upgrade. It looks like I am more up to date than those previous questions...

When you do this:

sudo curl http://npmjs.org/install.sh | sh

You will run curl as root, but sh as your current user. You should do this instead:

curl http://npmjs.org/install.sh | sudo sh

And all will be well.
