What is the best/safest way to reinstall Homebrew?

Question

I am getting issues with permissions in Homebrew: After I installed Node and tried to install npm using the curl command Homebrew tells you to use, it would fail due to EACC

Answer 1

For Mac OS X Mojave and above

To Uninstall Homebrew, run following command:

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

To Install Homebrew, run following command:

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

And if you run into Permission denied issue, try running this command followed by install command again:

sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*
