python - from django.db import utils ImportError 无法导入名称 utils？

Question

我在普通的 python shell 中，在尝试导入我的项目模型时遇到此错误:

from results.models import TestResult  

Traceback (most recent call last):  
  File "C:\Program Files (x86)\Wing IDE 3.2\src\debug\tserver\_sandbox.py", line 1, in <module>  
    # Used internally for debug sandbox under external interpreter  
  File "C:\Users\audrey_moreau\myProject\results\models.py", line 1, in <module>  
    from django.db import models  
  File "c:\Python27\Lib\site-packages\django\db\__init__.py", line 40, in <module>  
    backend = load_backend(connection.settings_dict['ENGINE'])  
  File "c:\Python27\Lib\site-packages\django\db\__init__.py", line 34, in __getattr__  
    return getattr(connections[DEFAULT_DB_ALIAS], item)  
  File "c:\Python27\Lib\site-packages\django\db\utils.py", line 92, in __getitem__  
    backend = load_backend(db['ENGINE'])  
  File "c:\Python27\Lib\site-packages\django\db\utils.py", line 54, in load_backend  
    return import_module('.base', backend_name)  
  File "c:\Python27\Lib\site-packages\django\utils\importlib.py", line 35, in import_module  
    __import__(name)  
  File "c:\Python27\Lib\site-packages\django\db\backends\sqlite3\base.py", line 14, in <module>  
    from django.db import utils  
ImportError: cannot import name utils

谁能指点一下如何解决这个问题？我正在使用 Python 2.7。

我有这个错误，它是由 django_nose 引起的。我试图从 settings.py 导入 django_nose 以确定它是否存在于系统中，如下所示:

try:
    import django_nose
    INSTALLED_APPS += ['django_nose']
    TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
except ImportError:
    pass

我修改为

from imp import find_module
try:
    find_module('django_nose')
    INSTALLED_APPS += ['django_nose']
    TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
except ImportError:
    pass

我的问题已经解决了...
