"Please try running this command again as Root/Administrator" error when trying to install LESS

Question

I'm trying to install LESS on my machine and have installed node already. However, when I enter "node install -g less" I get the following error and am not sure what to do?

FPaulMAC:bin paul$ npm install -g less npm ERR!

Re Explosion Pills "An installation can run arbitrary scripts and running it with sudo can be extremely dangerous!"

Seems like using sudo is the wrong way of doing it.

"Change the owner of the files in your /usr/local folder to the current user:"

sudo chown -R $USER /usr/local 

Then run the install

node install -g less
