Answer 1

I like to use ubuntu groups to achieve this instead of changing owner. Its quite simple.

1. First install nodejs and npm using apt-get

   sudo apt-get update && sudo apt-get install nodejs npm

2. Figure out who is logged in i.e username, run following command to see it in terminal

   whoami

3. You can see the list of groups you are assigned by using a very simple command, normally the first group is your username itself

   groups

4. Run following to allow access to logged in user

   sudo chmod 777 -R /usr/local && sudo chgrp $(whoami) -R /usr/local

5. Update npm and nodejs

   npm install -g npm

You are allset, your user can run npm commands without sudo
