kann manage.py runserver nicht ausführen

Question

Unten ist das Problem, das ich beim Ausführen des Servers konfrontiert bin. Ich kann manage.py runserver nicht starten. Ich benutze sqlite3 Datenbank. Ich versuche, eine ganz einfache Anwendung auszuführen. Systemkonfigurationen: Windows 10, Python 2.7.

Answer 1

deutlich Ihre Fehler Zurückverfolgungs besagt, dass Ihr SECRET_KEY leer

Erhöhung ImproperlyConfigured ("The secret_key Einstellung muss nicht leer sein. ") django.core.exceptions.ImproperlyConfigured: Die Einstellung SECRET_KEY darf nicht leer sein.

generieren einen neuen, können Sie diese verwenden

""" 
Pseudo-random django secret key generator. 
- Does print SECRET key to terminal which can be seen as unsafe. 
""" 
from __future__ import print_function 
import string 
import random 


# Get ascii Characters numbers and punctuation (minus quote characters as they could terminate string). 
chars = ''.join([string.ascii_letters, string.digits, string.punctuation]).replace('\'', '').replace('"', '').replace('\\', '') 

SECRET_KEY = ''.join([random.SystemRandom().choice(chars) for i in range(50)]) 

print(SECRET_KEY) 

diese Datei in secret_key.py speichern und tun python secret_key.py, wird es generieren Sie einen neuen SECRET KEY, dann kopieren Sie einfach neue SECRET_KEY in dir settings.py sind Datei.
