Homebrew — The Missing Package Manager for macOS and Linux

Homebrew is the missing package manager for macOS (and Linux). Installs CLI tools, libraries, and GUI apps (casks) that Apple or your Linux distro did not include. The de facto way developers set up their Mac development environment.

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Common commands:

brew install node                          # Install CLI tool
brew install --cask firefox                # Install GUI app
brew upgrade                               # Upgrade all
brew update                                # Update formulae list
brew list                                  # List installed
brew search redis                          # Search
brew info node                             # Package details
brew uninstall node                        # Remove
brew cleanup                               # Remove old versions
brew doctor                                # Diagnose issues
brew bundle dump                           # Export Brewfile
brew bundle install                        # Install from Brewfile

Brewfile (version-control your setup):

# Brewfile
tap "homebrew/bundle"

brew "git"
brew "node"
brew "go"
brew "rust"
brew "fzf"
brew "ripgrep"
brew "bat"
brew "eza"
brew "zoxide"
brew "starship"

cask "visual-studio-code"
cask "alacritty"
cask "ghostty"
cask "docker"
cask "firefox"
Intro

Homebrew is the missing package manager for macOS (and Linux). Created by Max Howell in 2009. Installs packages into their own directory and symlinks into /usr/local (Intel) or /opt/homebrew (Apple Silicon). Also manages GUI apps via Casks. Over 10,000 formulae and 8,000 casks available.

What Homebrew Does

  • Formulae — CLI tools and libraries (brew install)
  • Casks — GUI macOS applications (brew install --cask)
  • Taps — third-party repos for additional packages
  • Bottles — pre-built binaries for fast installs
  • Brewfile — declarative dependency management
  • Auto-update — background formula updates
  • Cleanup — remove old versions
  • Doctor — diagnose environment issues
  • Linuxbrew — works on Linux too

Architecture

Formulae are Ruby scripts describing how to download, build, and install a package. Bottles are pre-compiled binaries hosted on GitHub Packages (or Bintray). Homebrew stores everything under its prefix (/opt/homebrew on Apple Silicon) and symlinks into PATH.

Self-Hosting

Package manager — installs on user machine.

Key Features

  • 10,000+ CLI formulae
  • 8,000+ GUI casks
  • Pre-built bottles (fast installs)
  • Brewfile for reproducible setups
  • Third-party taps
  • Works on macOS and Linux
  • Auto-update
  • brew doctor diagnostics
  • Version pinning
  • Bundle support

Comparison

Manager Platform GUI Apps Scope
Homebrew macOS + Linux Casks General
MacPorts macOS No General
apt Debian/Ubuntu Via snap System
dnf Fedora/RHEL Via flatpak System
Scoop Windows Yes General
Chocolatey Windows Yes General
Nix Any Yes Reproducible

常见问题 FAQ

Q: Intel vs Apple Silicon？ A: Apple Silicon 安装到 /opt/homebrew；Intel 安装到 /usr/local。Homebrew 自动检测。Rosetta 2 下可以跑 x86 Homebrew（但不推荐）。

Q: 安全吗？ A: Homebrew 官方 formula 都经过 review。brew audit 检查合规。第三方 tap 安全性取决于 tap 维护者。

Q: 怎么管理多版本？ A: brew install node@18、brew link --overwrite node@18。更复杂的版本管理用 mise、asdf 或 nvm。
