Bower Installation Errors

Question

Now I have installed Node and Npm and I run this command in terminal (yes I am on a mac):

npm install -g bower

Which follows with this output from the terminal:

npm http GET https://registry.npmjs.org/bower

You need root access or permissions to install globally! Try :

 sudo npm install -g bower
