Thank you for making this

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!
