Django(Django错误整理)
1. Settings cannot be imported, because environment variable
DJANGO_SETTINGS_MODULE is undefined.
解决方法:

   >>> from django.template import Template, Context    >>> from django.conf import settings   >>> settings.configure() //添加这两句   >>> t = Template('My name is {{ my_name }}.')    >>> c = Context({'my_name': 'Daryl Spitzer'})    >>> t.render(c)   

其实还有一种方法，可以省去添加这两句:
$ cd ~//djcode/mysite
$ python manage.py shell
这之后也同样启动了一个python交互器，只不过它告诉了django使用哪些配置文件:

   >>> from django.template import Template   >>> t = Template('My name is {{ name }}.')   >>> print t
