Question

我正在尝试在Django开始一个项目，但我一开始就碰壁了。每当我在没有命令的情况下运行django-admin时，我会在帮助消息后收到此通知：

Note that only Django core commands are listed as settings are not properly configured (error: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.).

每当我尝试使用runserver等命令运行它或manage.py时，我得到：

python manage.py runserver
Traceback (most recent call last):


File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/home/castro/Code/django_tests/tutorial/lib/python3.6/site-packages/django/core/management/__init__.py", line 363, in execute_from_command_line
    utility.execute()

    output = self.handle(*args, **options)

    if not settings.DEBUG and not settings.ALLOWED_HOSTS:

    self._setup(name)

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

我不知道如何定义这个DJANGO_SETTINGS_MODULE，也不知道如何调用settings.configure（）。我已经尝试过这里提出的其他一些答案，但要么是一个不同的问题，要么我错过了一些非常明显的答案。

在manage.py文件的顶部附近，您应该看到此行，其中project是包含设置文件的项目名称。

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

如果项目不存在或路径错误，python manage.py将失败。

文件树看起来应该是这样的

.
├── manage.py
├── project
│   ├── settings.py

对于上下文，生成的manage.py包含以下行

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
# ... other code ...

DJANGO_SETTINGS_MODULE未定义
