Question

我正在处理Django教程并在运行初始python manage.py syncdb时收到以下错误：

Traceback (most recent call last):
File "manage.py", line 11, in <module>
  execute_manager(settings)
File "/Library/Python/2.6/site-packages/django/core/management/__init__.py", line 362 in execute_manager
  utility.execute()
File "/Library/Python/2.6/site-packages/django/core/management/__init__.py", line 303, in execute
  self.fetch_command(subcommand).run_from_argv(self.argv)
File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 195, in run_from_argv
  self.execute(*args, **options.__dict__)
File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 222, in execute
  output = self.handle(*args, **options)
File "/Library/Python/2.6/site-packages/django/core/management/base.py", line 351, in handle
  return self.handle_noargs(**options)
File "/Library/Python/2.6/site-packages/django/core/management/commands/syncdb.py", line 49, in handle_noargs
  cursor = connection.cursor()
File "/Library/Python/2.6/site-packages/django/db/backends/dummy/base.py", line 15, in complain
  raise ImproperlyConfigured, "You haven't set the DATABASE_ENGINE setting yet."
django.core.exceptions.ImproperlyConfigured: You haven't set the DATABASE_ENGINE setting yet.

我的settings.py看起来像：

DATABASES = {
  'default': {
    'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
    'NAME': 'dj_tut',                      # 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.
  }
}

我猜这很简单，但为什么不看引擎设置呢？

Answer 1

看起来您正在使用早期版本的Django。设置数据库配置的方式来自Django 1.2，但是你得到的错误来自1.1。如果您使用的是版本1.1，请使用this version of the tutorial。

Answer 2

'ENGINE': 'mysql',
'NAME': 'dj_tut',

您将需要设置用户和密码。

Answer 3

同样的问题经常发生在我身上，每次问题都是sttings.py和另一个模块之间的循环依赖。

Answer 4

在命令提示符下，您应该写：

edit settings.py

然后会有一个用于编辑

的新模块

settings.py

Django教程说我还没有设置DATABASE_ENGINE设置......但我有
