如何修复Django ImproperlyConfigured异常？

Question

因为我正在学习Django,所以我在virtualenv中使用了pip来安装Django.当Django Book告诉我在Python shell中键入它时,

from django import template
t = template.Template("My name is {{ name }}.")

我得到了这个例外.我不知道如何解决这个问题.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "django/template/base.py", line 123, in __init__
    if settings.TEMPLATE_DEBUG and origin is None:
  File "django/conf/__init__.py", line 53, in __getattr__
    self._setup(name)
  File "django/conf/__init__.py", line 46, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting TEMPLATE_DEBUG,
but settings are not configured. You must either define the environment variable
DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

有人可以带我走过吗？我正在使用Mac OS X 10.8

您似乎正在使用该命令运行python shell python.所以DJANGO_SETTINGS_MODULE变量不可用.使用运行特定于应用程序的python shell

python manage.py shell

manage.py设置DJANGO_SETTINGS_MODULE环境变量,使其指向项目的settings.py文件.
