Rust fails after Homebrew says its packages are satisfied

Page source

Source: Troubleshooting reference

Symptom: install/rust.sh reports Homebrew rustup not found even though brew list rustup and brew --prefix rustup succeed.

Root cause: Homebrew’s keg-only rustup formula removed rustup-init. Older bootstrap runs left ~/.local/cargo/bin/rustup pointing at the removed /opt/homebrew/bin/rustup-init, and rust.sh incorrectly required that removed binary before accepting the installed formula.

Confirm:

Terminal window
brew info rustup | grep -E 'keg-only|no longer provides'
readlink ~/.local/cargo/bin/rustup
ls "$(brew --prefix rustup)/bin/rustup"

Fix: update the checkout and run bash ~/dotfiles/install/rust.sh. The installer now links Homebrew’s individual keg wrappers into the managed Cargo bin directory and initializes stable with rustup toolchain install; it does not depend on rustup-init.
