In this guide I’ll show you how to install the package manager Bower on Mac OS X. Bower is a NodeJS application, so you’ll need to install the Node Package Manager npm first. npm is available as a package in the Homebrew repositories.

If you don’t have Homebrew installed, it’s probably time to do so and then install npm and bower:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install npm
npm install -g bower

In case you get the following error while installing the bower package, add the following lines to your /etc/services file:

fatal: Unable to look up github.com (port 9418) (nodename nor servname provided, or not known)

ntp             123/tcp
ntp             123/udp

Now that the installation is complete, run bower using bower.
