Following instructions work

Below are the steps to install Node.js from source (OSX/linux) You may/should issue all these cmds as yourself NOT root (sudo)

NOTE - this installs Node.js which gives you both node as well as npm, they come together per release.

to start fresh remove prior node and npm installs as well as these :

sudo mv ~/.npmrc ~/.npmrc_ignore
sudo mv ~/.npm   ~/.npm_ignore
sudo mv ~/tmp    ~/tmp_ignore
sudo mv ~/.npm-init.js ~/.npm-init.js_ignore

download source from : http://nodejs.org/download/

cd node-v0.10.33

define environment variable NODE_PATH as the dir for subsequent module installs

export NODE_PARENT=/some/desired/install/path_goes_here

export NODE_PARENT=/usr/local/bin/nodejs    # use this if you want to install as root (sudo)
export NODE_PARENT=${HOME}/nodejs-v0.10.33  # use this if you want to install modules as yourself

export PATH=${NODE_PARENT}/bin:${PATH}
export NODE_PATH=${NODE_PARENT}/lib/node_modules

./configure   --prefix=${NODE_PARENT}

make
make install

which puts it into dir defined by above --prefix

when you use syntax : npm install -g some_cool_module the -g for global installs it into dir $NODE_PATH and not your $PWD

Now put above three export xxx=yyy commands into your ~/.bashrc or some such to persist these environment variable changes

npm -v reports error when node.js has been installed
