install node and npm

gistfile1.txt

vim ~/.bashrc

make sure in your bashrc file you have the following:

export PATH=$HOME/local/bin:$PATH
export PATH="$PATH:$HOME/npm/bin"

# this one is optional, add it it doesn't work at the end
export NODE_PATH="$NODE_PATH:$HOME/npm/lib/node_modules"

install-node-and-npm.sh

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local or ./configure --prefix=$HOME/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl -L https://www.npmjs.com/install.sh | sh
