I get this error when I work in a virtual machine: a VMWare Ubuntu 12.04.5. Would you have any suggestions?
Thanks in advance!

Read the error:
Please try running this command again as root/Administrator
Try:
sudo npm install -g npm
And as #mscdex said, you have to upgrade you node version. it is really old.
