problem with python-snappy installation on a virtualenv

Inizia riproducendo l’installazione nel virtualenv Python 2.7 e ispeziona setup.py, snappy/snappymodule.cc e snappy/crc32c.c insieme agli errori di header e del compilatore riportati. Determina se il problema dipende dal packaging del progetto o è specifico dell’ambiente; il lavoro è completato quando il percorso di installazione supportato ha successo oppure sono documentati l’ambiente richiesto e la limitazione.

I tried to install python-snappy on a virtualenv with python 2.7. It failed
