Unter den vielen Paketen, die Benutzer für Scrapy installieren müssen, habe ich Probleme mit pyOpenSSL.Paketabhängigkeiten für Scrapy installieren
Wenn ich versuche, ein Tutorial Scrapy Projekt angelegt zu bekommen, bekomme ich diese folgende Ausgabe:

ImportError: No module named cryptography.hazmat.bindings.openssl.binding
Und wenn gegoogelt ich das letzte Fehler (kein Modul mit dem Namen cryptography.hazmat), habe ich ein paar erwähnt sehen von pyOpenSSL. Also ging ich weiter und versuchte easy_install pyOpenSSL==0.14
laufen, um sicherzustellen, es ist die neueste Version, aber wenn ich das tue, erhalte ich diese Ausgabe:

So bin ich ein wenig verloren, was ich tun müssen, um zu bekommen Scrapy up and running richtig
Ich habe wenig Python 32 sowie pyopenssl 32-Bit installiert. Nicht sicher, was sonst 64 Bit falsch sein könnte ... – simplycoding
