Installing Yeoman errors

I am new to Ubuntu and to Angular. I am attempting to set up a Yeoman framework. However each time I run the "yo" command. the following errors occur: ``` Error: EACCES, mkdir '/home/diarmuid/tmp/npm-2997-20XPEB7W' npm ERR! { [Error: EACCES, mkdir '/home/diarmuid/tmp/npm-2997-20XPEB7W'] npm ERR! errno: 3, npm ERR! code: 'EACCES', npm ERR! path: '/home/diarmuid/tmp/npm-2997-20XPEB7W', npm ERR! parent: 'davidmoshertutorial' } npm ERR! npm ERR! Please try running this command again as root/Administrator. npm ERR! System Linux 3.8.0-35-generic npm ERR! command "/usr/bin/node" "/usr/bin/npm" "install" npm ERR! cwd /home/diarmuid/AngularTutorial/DavidMosherTutorial npm ERR! node -v v0.10.25 npm ERR! npm -v 1.3.24 npm ERR! path /home/diarmuid/tmp/npm-2997-20XPEB7W npm ERR! code EACCES npm ERR! errno 3 ``` Does anyone understand how to solve this? I tried to run "sudo yo" however I got response to : ``` change to change where npm stores global packages by putting ~/npm/bin in your PATH and running: npm config set prefix ~/npm ``` I ran to gedit ~/.profile and edited the file to this: ``` # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH:/~/npm/bin" fi ``` I am obviously a bit lost. If anyone has any suggestions it would be much appreciated.
