NPM Errors when installing sails.js

I just did my first install of node.js on a windows 10 machine. I went to install sails.js by npm install sails -g and it is blowing out with the following errors:

$ npm install sails -g
npm ERR! Windows_NT 10.0.10586
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program 
Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" "sails" "-g"
npm ERR! node v6.11.0
npm ERR! npm  v3.10.10

npm ERR! Invalid name: "@sailshq/express"

Any ideas why it is doing this?
