Unable to install Heroku


I’m a newbie and doing the installing lesson. I have a problem trying to install Heroku. I type brew install heroku/brew/heroku and the terminal responds bash: brew: command not found. What am I doing wrong?? thank you for your time


What’s the output of brew help


again the same _brew: the command not found


Sounds like homebrew isn’t install then

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


Yeah that’s right!! I haven’t installed it, as I thought!! thank you so much
