I get prompt:

Answer 1

I ran into the error message issue trying to update Brew via another Mac user. When I tried entering the above sudo chown -R $USER /usr/local I got:

chown: /usr/local: Operation not permitted

I found this sudo chown -R $(whoami) $(brew --prefix)/* which allowed me to perform install of brew for separate Mac user.

Answer 2

You are getting permission denied when downloading the files into /usr/local.

This folder often belongs to root. This is a known issue with brew. Fix it by doing

sudo chown -R $(whoami) $(brew --prefix)/*

and then re-run the installer.

Answer 3

If nothing works, then just uninstall and install home-brew again.

Uninstall command:

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

Install command:

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

Answer 4

I could get it working with

sudo chown -R $USER /usr/local
