# Easily install new or old versions of Node.js on an OS X machine.
#
# Install: curl -o /usr/local/bin/install_node https://gist.github.com/raw/2569416/install_node.sh
#          chmod +x /usr/local/bin/install_node
#
# Usage: install_node 0.6.16
#
# Specify the version as the single argument, if you want to customize the
# cache directory, you can modify this file or prefix with:
#
# DIR=~/.cache install_node 0.6.16
#

# Configure the installer cache directory
DIR=~/.node
# Configure the target harddisk to install to
TARGET=/Volumes/Macintosh\ HD
# Pass version in as an argument
VER=$*

# If install file doesn't already exist, fetch it first
if [ ! -f ~/.node/$VER.pkg ]; then
  # Fetch the package into a hidden directory
  curl --create-dirs -o $DIR/$VER.pkg \
    http://nodejs.org/dist/v$VER/node-v$VER.pkg
fi

# Invoke the installer
sudo installer -pkg $DIR/$VER.pkg -target $TARGET

L34 should be -target $TARGET
