嗨，提前感谢您的帮助。我刚刚开始学习 Python 和 Django，并且一直在尝试在 djangoproject.com 中设置教程。我一直在尝试设置服务器，但不断收到此错误：

Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x108826090>>
Traceback (most recent call last):

backend = load_backend(db['ENGINE'])
File "/Library/Python/2.7/site-packages/django/db/utils.py", line 44, in load_backend
raise ImproperlyConfigured(error_msg)
django.core.exceptions.ImproperlyConfigured: 'django.db.sqlite3.db' isn't an available database backend.
Try using django.db.backends.XXX, where XXX is one of:
'dummy', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: No module named sqlite3.db.base

我尝试使用聚光灯定位 sqlite3.db.base，但找不到该模块。当我转到终端并导入 sys 并导入 sqlite3 时，我没有收到任何错误。终端中的 Sys.path 给了我：

['',

'/Library/Python/2.7/site-packages', 
'/Library/Python/2.7/site-packages/setuptools-0.6c11-py2.7.egg-info']

目前我的 settings.py 设置为：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.sqlite3.db', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7',      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

再次感谢！

你破坏了ENGINE设置。应该是django.db.backends.sqlite3。

那不是关于进口的。您在 ENGINE 设置中输入错误。它必须是这样的：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.                                                              
        'NAME': join(CURRENT_DIR, 'db/cms.db'), # Or path to database file if using sqlite3.                                                                              
        'USER': '',                      # Not used with sqlite3.                                                                                                         
        'PASSWORD': '',                  # Not used with sqlite3.                                                                                                         
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.                                                                      
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.                                                                        
    }
}
