Quindi tra i molti pacchetti che gli utenti devono installare per Scrapy, penso di avere problemi con pyOpenSSL.Installare le dipendenze del pacchetto per Scrapy
Quando cerco di ottenere un progetto Scrapy esercitazione creato, ottengo questo output seguente:

E quando Ho cercato su google che ultimo errore (senza modulo denominato cryptography.hazmat), vedo un paio di menzioni di pyOpenSSL. Così sono andato avanti e ho cercato in esecuzione easy_install pyOpenSSL==0.14
per assicurarsi che sia l'ultima versione, ma quando lo faccio, ottengo questo output:

Quindi sono un po 'perso di ciò che devo fare per ottenere Scrapy installato e funzionante correttamente
ho Python a 32 bit installato così come pyOpenSSL 32 bit. Non so cos'altro potrebbe essere erroneamente 64 bit ... – simplycoding
