Language Runtimes

Installs the full runtime lineup — Node, Python, Java, Go, Rust, Ruby on request — under the modern manager set: mise for everything except Python (uv) and Rust (rustup). One manager per runtime; competing managers racing to put shims first in PATH is the top cause of "node is weird" machines.

When NOT to use

• Project-level deps (npm install, venvs, requirements.txt) → native
• pnpm/corepack, databases → web-dev-setup
• JDK specifically for Android Studio/Gradle → mobile-dev-setup
• Upgrading installed runtimes → mac-maintenance

Prerequisites

brew present (→ homebrew-setup).
