django.core.exceptions.Improperly在尝试使用nose运行测试时配置（不在django项目中）

Question

我已经创建了一个项目来找出适合我的其他python项目的项目结构。

我真正想做的是进行一些测试。

example.py看起来像这样

import unittest
from A.A import A

__author__ = 'michael'


class ExampleTest(unittest.TestCase):
    def setUp(self):
        self.a = A()
        pass

    def test_stub(self):
        self.assertEquals(self.a.foo(), 'foo')

if __name__ == '__main__':
    unittest.main()

当我跑步时

/Temp $ nosetests

我得到django例外。

Traceback (most recent call last):

    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

我根本得不到它。 django与它有什么关系？

EDIT1：

无法显示代码，因为我已经学会了如何使用unittest运行测试并删除了这个项目。

但我向你保证，A的代码只是关于使用B.像

这样的东西

A类（）：  def __init（self）：   self.b = B（）

def foo（self）：   b.foo（）

B只是一个带有foo方法的类，它打印字符串'foo'。

从第

行开始

File "/usr/local/lib/python2.7/dist-packages/queries/nose_plugin.py", line 22, in configure
    connection.use_debug_cursor = True

好像你已经安装了django-dynamic-fixture。这个包安装了一个使用django ORM的nose_plugin。

• 禁用django-dynamic-fixture（我不知道该怎么做）或
• 卸载django-dynamic-fixture或
• 在孤立的虚拟工作中工作。
