NPM permission issue resolution

NPMPermissionIssues.txt

As per photusenigma at: https://github.com/npm/npm/issues/4815

Run these commands in a terminal window (note - DON'T replace the $USER part...thats a linux command to get your user!):

sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/local/lib/node_modules
...and...if you're on a mac (like I am), and still see errors after running these commands, then run this last one and you should be good. (Recommend you try testing before you do this one. I don't like changing the permissions on the ENTIRE /usr/local directory unless it really seems necessary!)

sudo chown -R $USER /usr/local





for yeoman I needed with Username being yours:
sudo chmod g+rwx  /Users/Username/.config /Users/Username/.config/configstore
