Django (1.5)对我来说很好,但是当我启动Python解释器(Python3)来检查一些东西时,我得到了最奇怪的错误,当我尝试导入- from django.contrib.auth.models import User
-
Traceback (most recent call last):
File "/usr/local/lib/python3.2/dist-packages/django/conf/__init__.py", line 36, in _setup
settings_module = os.environ[ENVIRONMENT_VARIABLE]
File "/usr/lib/python3.2/os.py", line 450, in __getitem__
value = self._data[self.encodekey(key)]
KeyError: b'DJANGO_SETTINGS_MODULE'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

File "/usr/local/lib/python3.2/dist-packages/django/contrib/auth/models.py", line 8, in <module>

if settings.DATABASES and DEFAULT_DB_ALIAS not in settings.DATABASES:
File "/usr/local/lib/python3.2/dist-packages/django/conf/__init__.py", line 52, in __getattr__
self._setup(name)
File "/usr/local/lib/python3.2/dist-packages/django/conf/__init__.py", line 45, in _setup
% (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.
当它在Python解释器之外工作得很好时,它怎么会被错误地配置呢?在我的Django设置中,DATABASES
设置为:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'django_db', # Or path to database file if using sqlite3.
# The following settings are not used with sqlite3:
'USER': 'zamphatta',
'PASSWORD': 'mypassword91',
'HOST': '', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
'PORT': '', # Set to empty string for default.
}
}
...how是否配置不正确?

在python shell/ipython中执行以下操作:
from django.conf import settings
settings.configure()

在Django1.9上,我尝试了django-admin runserver
,得到了同样的错误,但当我使用python manage.py runserver
时,我得到了预期的结果。这可能会为很多人解决这个错误!

在我自己的例子中,在python2.7.11上运行的django 1.10.1中,我试图使用项目目录中的django-admin runserver
而不是manage.py runserver
来启动服务器。
