Run NPM without sudo, installed on mac with brew

gistfile1.sh

# using Homebrew
 
# Note: `brew install npm` has problems, as of 2010-12-30.
# hopefully it will eventually be good and happy.
# As of [email protected], however, this is an option
 
PREFIX=$(brew --prefix)
 
# take ownership
# this will also let homebrew work without using sudo
# please don't do this if you don't know what it does!
sudo mkdir -p $PREFIX/{share/man,bin,lib/node,include/node}
sudo chown -R $USER $PREFIX/{share/man,bin,lib/node,lib/node_modules,include/node}
 
brew install node
 
# now install npm
# prefix will default to $(brew --prefix)
