Error installing PyBabeljs on virtualenv

Inizia da setup.py intorno alla riga 20 e dai metadati del pacchetto che producono setup.cfg; riproduci l’errore di installazione di virtualenv mostrato nel report. Verifica se le modifiche proposte a zip_safe e keywords rimuovono l’errore e l’avviso relativo a dati marshal non validi, quindi conferma che l’installazione riesca.

I think that adding zip_safe=True it's fixed. Also, changing keywords type (from tuple to list), the warning shown Warning: 'keywords' should be a list, got type 'tuple' can be avoided.
