Question

尝试运行一些测试，我遇到了这个错误，即使用Python 2.7.3和Django 1.5。

python -m unittest discover
E

ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

test_select_nodes_from_rectangle.py

from django.core.context_processors import csrf
....
....
import random
import unittest

....
....
....

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

Answer 1

根据错误消息中的建议设置环境变量，让Django知道哪个文件包含项目设置：

DJANGO_SETTINGS_MODULE=settings.module python -m unittest discover

或者启动这样的测试：

./manage.py test

ImportError：导入测试模块失败
