Django manage.py 迁移 ImportError

Question

我正在阅读 Django 教程（1.8 版），当我尝试使用命令 python manage.py migrate

为 INSTALLED_APPS 创建数据库时

我最终收到以下导入错误：

File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 338, in execute_from_command_line
utility.execute()
File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 303, in execute
settings.INSTALLED_APPS
File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 48, in __getattr__
self._setup(name)
File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 44, in _setup
self._wrapped = Settings(settings_module)
File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 92, in __init__
mod = importlib.import_module(self.SETTINGS_MODULE)
File "C:\Python27\lib\importlib\__init__.py", line 37, in import_module
__import__(name)
ImportError: Import by filename is not supported.

我的 DJANGO_SETTINGS_MODULE 链接到正确的位置 ...Django\mysite\mysite\settings.py

这是我的 settings.py:

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Answer 1

ImportError: Import by filename is not supported.

您似乎在尝试导入应用程序并指定文件名而不是名称。你能 post settings.py 吗？你必须这样写：

INSTALLED_APPS = (

... snip ...

   'polls',
)

不是这样的：

INSTALLED_APPS = (

... snip ...

   'polls.py',
)

Answer 2

错误实际上与INSTALLED_APPS无关；如果您注意到，错误发生在 mod = importlib.import_module(self.SETTINGS_MODULE)，这意味着它无法导入您的设置模块。

在这种情况下，问题是您的 DJANGO_SETTINGS_MODULE 需要是一个带点的 Python 路径，而不是文件系统路径。我对您的需求的最佳猜测是：

DJANGO_SETTINGS_MODULE="mysite.mysite.settings"
