当我django-admin使用--settings开关运行时，它失败了：

(env) $ django-admin help --settings=myapp.settings
Traceback (most recent call last):
  File "/srv/http/myapp/env/bin/django-admin", line 11, in <module>
    sys.exit(execute_from_command_line())
  File "/srv/http/myapp/env/lib/python3.5/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line
    utility.execute()

    mod = importlib.import_module(self.SETTINGS_MODULE)

    return _bootstrap._gcd_import(name[level:], package, level)

ImportError: No module named 'myapp'

(env) $ ls myapp/settings.py
myapp/settings.py

但manage.py工作得很好。为了清楚起见，我想有额外settings.py的开发环境。

此外，从此脚本导入设置：

#!/usr/bin/env python
import myapp.settings

也可以。

好吧，文档确实说：

manage.py与您做同样的事情，django-admin但会为您处理一些事情：

  • 它将您项目的包放在sys.path.

  • 它设置DJANGO_SETTINGS_MODULE环境变量，使其指向您的项目settings.py文件。

但它也说：

如果需要在多个 Django 设置文件之间切换，请使用django-adminwithDJANGO_SETTINGS_MODULE或--settings命令行选项。

所有示例都遵循以下原则：

$ django-admin migrate --settings=mysite.settings

事情是为了让它工作你的项目目录必须在sys.path. 实现这一目标的一种方法是：

PYTHONPATH=/path/to/project django-admin help --settings=myapp.settings

或者你可以使用--pythonpath开关，或者PYTHONPATH提前设置。
