## Install NodeJS and NPM

### Ubuntu NodeJS Packages

    apt-get update; apt-get install nodejs npm`
    nodejs --version
        v0.10.25
    which nodejs
        /usr/bin/nodejs

`which node`
> So pretty useless... Instead:

1. cd /opt
1. wget http://nodejs.org/dist/v0.10.33/node-v0.10.33-linux-x64.tar.gz
1. tar -xf node-v0.10.33-linux-x64.tar.gz
1. ln -s /opt/node-v0.10.33-linux-x64/bin/node /usr/bin/node


WTF: get the latest npm 2.0 using: npm -g install npm@2

npm --version
npm config --list



### Source


1. sudo apt-get install build-essential libssl-dev
1. cd /opt
1. wget http://nodejs.org/dist/v0.10.33/node-v0.10.33-linux-x64.tar.gz
