You may already have Homebrew installed. Let's see if you do. Type
which brew
If you get an error message, then we need to install it. Follow below to install or skip to Update Homebrew if it is installed.
Now it's time to install Homebrew, the de facto package manager for OS X. If you've never heard of a package manager, think of it as an App Store of free command line programs.
To get started, run the following command.
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/install/master/install)"
TIP: Be sure to agree when asked to install the XCode CommandLine Tools. This takes about 30 minutes to download and install on average.
If you've previously installed Homebrew, now's a good time to update it by running the following command.
brew update
If it's been a while since the last update, you'll see something like this.
Otherwise, you'll see something like this.
TIP: Run this command periodically as Homebrew doesn't auto-update itself. 😓
To verify Homebrew is installed correctly, run the following command.
brew doctor
And you'll see something like this.
