Install npm and node locally without sudo or root privilege

Trying to play with node and meteor in my own directory with invoking root privilege

By default all these packages will assume default of /usr/local. We need to change that

In .bash_profile, add:

export npm_config_prefix=$HOME/local # For npm
export PREFIX=$HOME/local
export N_PREFIX=$HOME/local # For n


Make sure the changes are in effect by running:  

. ~/.bash_profile 


For npm

1. Download the install script from https://npmjs.org/install.sh. At the time of writing, this URL issues a 301 redirect, so we need the '-L' switch to follow the redirection. To specify the prefix, we need 'npm_config_prefix' (covered in .bash_profile)

curl -L https://npmjs.org/install.sh | /bin/sh   

For node or other packages installable by npm

1. Node is installed via npm and the prefix is specified by N_PREFIX (covered in .bash_profile)

npm install -g n

2. Install the versions
n stable

Do note the above: npm install -g means the package will be installed relative to the current location
