cd /opt/homebrew/bin/
PATH=$PATH:/opt/homebrew/bin
cd
touch .zshrc
echo export PATH=$PATH:/opt/homebrew/bin >> .zshrc
Run the commands in that order in terminal, you’ll be editing the path and creating the missing .zshrc file, exporting the path to this new file.
Now you should be able to use:
brew doctor
It should say: “Your system is ready to brew.”
