What are common errors when running the CLI on macOS?

Answer

Common issues: 'command not found: vibgrate' (package not installed globally or npx not used). Permission denied (use sudo cautiously or fix with sudo chown -R $(whoami) ~/.npm). EACCES errors (npm cache permissions — run npm cache clean --force). SSL certificate errors (try npm config set strict-ssl false temporarily). xcode-select errors (run xcode-select --install).
