after you upgrade your ruby to v3.1 via brew,
you will find that you cannot use vim.

$ vi
dyld[82297]: Library not loaded: /opt/homebrew/opt/ruby/lib/libruby.3.0.dylib
  Referenced from: /opt/homebrew/Cellar/vim/8.2.3500/bin/vim
  Reason: tried: '/opt/homebrew/opt/ruby/lib/libruby.3.0.dylib' (no such file), '/usr/local/lib/libruby.3.0.dylib' (no such file), '/usr/lib/libruby.3.0.dylib' (no such file), '/opt/homebrew/Cellar/ruby/3.1.2/lib/libruby.3.0.dylib' (no such file), '/usr/local/lib/libruby.3.0.dylib' (no such file), '/usr/lib/libruby.3.0.dylib' (no such file)
[1]    82297 abort      vi

then you search stack overflow and many sites, they cannot give you an answer.
eg. https://superuser.com/questions/1096438/brew-upgrade-broke-vim-on-os-x-dyld-library-not-loaded
they will tell you reinstall vim and ruby or link ruby etc.
no, they do not work.

here are the answer.

$ ln -s /opt/homebrew/opt/ruby/lib/libruby.3.1.dylib /opt/homebrew/opt/ruby/lib/libruby.3.0.dylib
$ ls -al /opt/homebrew/opt/ruby/lib
