Common Issues

If you encounter permission errors when running zb install, this usually means zerobrew doesn’t have write access to the installation directory.Solution:
  • Ensure you have proper permissions for the installation prefix
  • On macOS, zerobrew defaults to /opt/zerobrew to stay within the 13-character Mach-O path limit
  • You can customize the installation directory during setup
  • Avoid using sudo with zerobrew commands
Download issues can occur due to network problems or unavailable bottles.Solution:
  • Check your internet connection
  • Try again after a few minutes (the Homebrew API might be temporarily unavailable)
  • If no bottle is available for your platform, use the --build-from-source or -s flag: 
    zb install <package> --build-from-source
  • This will compile the package from source locally
If zerobrew commands aren’t recognized after installation, your shell may not be properly configured.Solution:
  • zerobrew should automatically configure your shell during installation
  • Supported shells: bash, zsh, and fish
  • Restart your terminal or run: 
    source ~/.bashrc  # for bash
source ~/.zshrc   # for zsh
  • For fish, run: source ~/.config/fish/config.fish
On macOS ARM (M1/M2/M3), you might see an error about missing zbx-darwin-arm64.Solution:
  • This was fixed in recent releases where zbx binaries are now included
  • Update to the latest version of zerobrew
  • Run zb update or reinstall zerobrew from the latest release
Some packages may fail to install with errors related to binary patching.Solution:
  • zerobrew automatically patches Mach-O binaries to work with custom prefixes
  • Recent versions preserve the execute bit when patching
  • If the new prefix is longer than the old one, patching is skipped automatically
  • Ensure you’re using the latest version of zerobrew
Issues installing packages from external taps or cask formulas.Solution:
  • zerobrew now supports external taps and casks with safer install/uninstall behavior
  • Make sure you’re running the latest version
  • For GitHub releases, zerobrew will attempt to install directly with a clone fallback
Installations taking longer than expected.Solution:
  • zerobrew is optimized for speed with parallel downloads and minimal overhead
  • Check your network connection speed
  • Clear the cache and try again: zb cleanup
  • Building from source will naturally take longer than installing bottles
