Installing on macOS with Homebrew

Homebrew is another open source software package manager for macOS, which some say is the perfect replacement for MacPorts. It is available through their home page at http://brew.sh/. After installing Homebrew using the instructions on their website and ensuring that Homebrew is correctly set up, use the following:

$ brew update
... long wait and lots of output
$ brew search node
==> Searching local taps...
node  libbitcoin-node node-build node@6 nodeenv
leafnode llnode node@4 nodebrew nodenv
==> Searching taps on GitHub...
caskroom/cask/node-profiler
==> Searching blacklisted, migrated and deleted formulae...

Then, install it this way:

$ brew install node
...
==> Installing node
==> Downloading https://homebrew.bintray.com/bottles/node-8.9.1.el_capitan.bottle.tar.gz
