Macvim from Homebrew formula missing ruby@4.0

Bắt đầu bằng cách tái hiện lỗi với brew install macvim, sau đó kiểm tra công thức Homebrew và các điểm vào của dependency hoặc build để tìm thư viện ruby@4.0 bị thiếu. Công việc được hoàn tất khi MacVim khởi chạy sạch thành công cả qua MacVim.app lẫn mvim/gvim, kể cả khi dùng --clean.

Steps to reproduce

Install macvim via homebrew via brew install macvim and then either launch the macvim via GUI or terminal. The error message I got is:

dyld[20899]: Library not loaded: /opt/homebrew/opt/ruby@4.0/lib/libruby.4.0.dylib

Vim and MacVim configuration where issue is reproducable

No response

How was MacVim launched?

• by launching MacVim.app in macOS (by using the Dock, Spotlight, or the open command)
• by running mvim/gvim in the terminal

Issue has been tested with clean configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution). You can also use the File → "New Clean Window" menu item within MacVim.
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)
