Rspec/Capybara caricamento in corso, circolare richiesta considerata dannosa

Question

Non sono sicuro se si tratta di un problema di Capybara, ma ho appena effettuato una nuova installazione di Rails (4.1.1) e Rspec Rails (3.0.1) e vorrei utilizzare Capybara (2.3.0), ma non averlo mai usato mi sto imbattendo in problemi. Ho creato una "specifica" in spec/features e la specifica stessa viene eseguita e trasmessa come previsto, ma ottengo i seguenti "avvertimenti" quando viene eseguito rspec. Qualche idea? Devo solo disabilitare gli avvisi a livello di rubino o qualcosa del genere?

Rimuovere --warnings da .rspec. Il generatore in rspec 3.0.0 includeva questa impostazione, ma ci siamo resi conto che si trattava di un errore: mentre è opportuno incoraggiare gli utenti a scrivere codice privo di avvisi, è difficile per gli utenti ottenere questi avvisi senza essere sicuri del perché.
