Installing Heroku CLI on macOS Catalina Let me just state what has already been tried and what is already known. When I downloaded and tried to run the installer, the following error pops up:


  "Currently, the macOS installer on Catalina displays an “unknown author” warning. We are working to address this."


So I tried other methods such as running the following in the terminal:

sudo snap install --classic heroku


and

curl https://cli-assets.heroku.com/install.sh | sh


but both required some sort of superuser access, password required (which I have no idea what it is).

I have also downloaded the macOS tarballs but I have no idea how it works too.

Could somebody provide some advice? Thank you!
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 &amp;&amp; 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.
