Install Native Homebrew on Apple Silicon M1

homebrew_m1.sh

# We'll be installing Homebrew in the /opt directory.
cd /opt

# Create a directory for Homebrew. This requires root permissions.
sudo mkdir homebrew

# Make us the owner of the directory so that we no longer require root permissions.
sudo chown -R $(whoami) /opt/homebrew

# Download and unzip Homebrew. This command can be found at https://docs.brew.sh/Installation.
curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

# Add the Homebrew bin directory to the PATH. If you don't use zsh, you'll need to do this yourself.
echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

Thanks for this! It's great...except I get this ("No such file or directory") every time I do anything with brew, for example %brew doctor
% brew doctor
/opt/homebrew/bin/brew: line 11: cd: /usr/local/Homebrew/bin: No such file or directory
Your system is ready to brew.
Any thoughts? brew works fine (or does it?) but...that message!
