I'm trying to follow this guide and install Heroku CLI on my Mac. https://devcenter.heroku.com/articles/heroku-cli#download-and-install
When I typed
brew tap heroku/brew && brew install heroku
The terminal returns
bash: brew: command not found
What should I do here?
are u already install brew on your system? if not try read this :
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)
paste that in a macOS Terminal or Linux shell prompt.
after install brew, try again install heroku cli
