ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined. 

错误解决方法

 

方法一： 
>>> 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)
