Meaning

The path in the message tells what's missing. Reinstall the dependency (brew install openssl@1.1) or the program itself so it relinks (brew reinstall PACKAGE). Version bumps (openssl, icu4c, readline) frequently break old binaries. otool -L binary lists linked libraries.

Common causes

  • Homebrew upgrade removed an old library version
  • Dependency uninstalled/pruned
  • Intel vs ARM prefix mismatch
  • Binary built against a different install path
  • Broken symlink in /usr/local/opt

⚡ Quick fix

  1. brew reinstall PACKAGE
  2. Install the specific older dependency named in the error
  3. Check links: otool -L $(which program)

Detailed fix by platform

macOS

  1. otool -L $(which program) and brew list --versions openssl@3

How to diagnose

  1. Library — Path in the message?
  2. Cause — Upgrade or removal?
  3. Prefix — Intel or ARM?
