Question

我一直在使用Django超过一年，并且从未需要'定义环境变量DJANGO_SETTINGS_MODULE，因为我被要求在以下错误消息中执行：

E
======================================================================
ERROR: setUpClass (__main__.SmokeTest)

Traceback (most recent call last):

    % (desc, ENVIRONMENT_VARIABLE))
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.

我正在使用Windows命令行。

我试过了

from django.conf import settings

settings.configure()

解释here，但这没有用。

有谁知道如何让它发挥作用？

Answer 1

“命令行中的@brunodesthuilliers我在我的app目录中，运行python tests.py”

那不会起作用（至少不那么容易）。为什么不使用内置管理“测试”命令？

 #> cd your/project/root 
 #> python manage.py test

cf https://docs.djangoproject.com/en/1.9/topics/testing/

Answer 2

您确定在 manage.py 中有类似的内容

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "projectname.settings")

MARS 4.5

django设置的环境变量？
