Installing Heroku CLI on macOS Catalina

The Heroku CLI is available to install via Homebrew. Homebrew is a 3rd party, community supported package manager for macOS.

If you have Homebrew installed, simply run the following command-line to install Heroku CLI (instructions here):

brew tap heroku/brew && brew install heroku

If you do not already have Homebrew installed, install it by running the following command-line (instructions here):

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Using Homebrew provides a seamless and hassle-free experience for installing supported 3rd party packages such as the one in question.
