AppEngine延迟库中的PermanentTaskFailure

我正在使用应用引擎和延迟库。但偶尔我的任务会失败,并出现以下错误:

Permanent failure attempting to execute task
Traceback (most recent call last):
  File "/base/python_lib/versions/1/google/appengine/ext/deferred/deferred.py", 
    line 256, in post
      run(self.request.body)
  File "/base/python_lib/versions/1/google/appengine/ext/deferred/deferred.py", 
    line 122, in run
      raise PermanentTaskFailure(e)
PermanentTaskFailure: Environment variable DJANGO_SETTINGS_MODULE is undefined.

我找到了一个 post 解决方案是:

from google.appengine.ext.webapp import template 

但是我没有使用webapp框架,我使用的是django。我可以试一试吗?
