Question

我在WinXP上使用以下命令並出現錯誤，但在MacOS和Linux上正常工作，非常感謝您的幫助。

C:\Documents and Settings\Administrator\Sites\team_track>manage.py syncdb --settings=local_settings

You just installed Django's auth system, which means you don't have any superusers defined. 
Would you like to create one now? (yes/no): yes 
Username (Leave blank to use 'administrator'): 
E-mail address: kam@kam.com 
Password: 
Password (again): 
Superuser created successfully.

這裏是我的manage.py是什麼樣子：

#!/usr/bin/env python 
import sys 
import os.path 

from django.core.management import execute_manager 
try: 
    import team_tracker.settings # Assumed to be in the same directory. 
except ImportError: 
    import sys 
    sys.stderr.write("Error: Can't find the file 'settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__) 
    sys.exit(1) 

if __name__ == "__main__": 
    execute_manager(team_tracker.settings) 

而且我local_settings.py駐留在根目錄：

from team_tracker.settings import * 

DEBUG = True 

#DATABASE_ENGINE = 'sqlite3' 
#DATABASE_NAME = 'caktus_website.db' 

DATABASE_ENGINE = 'sqlite3', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'. 
DATABASE_NAME = 'team_track.db' # Or path to database file if using sqlite3. 

最後我team_tracker/settings.py是這裏：

Answer 1

在local_settings.py：

DATABASE_ENGINE = 'sqlite3', 

這裏的逗號使得DATABASE_ENGINE一個元素，而不是字符串的元組。刪除它，它應該工作。
