You would need to specify more information in order to receive any advice. What platform are you on? What package manager would you like to use? Have you tried doing as instructed and specifying the tool manually?

You should install the package brew before. You can got it by sudo apt install linuxbrew-wrapper if the working system is Ubuntu.
