To install node js. I am referring this url https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-a-centos-7-server
but when I try extract source with this command tar xzvf node-v* && cd node-v*
I get error tar: node-v4.2.3-linux-x64/bin/npm: Cannot create symlink to../lib/node_modules/npm/bin/npm-cli.js': Protocol error`
