Django的manage.py迁移导入错误

我经历Django的教程（1.8版），当我尝试使用CMD python manage.py migrateDjango的manage.py迁移导入错误

我最终得到下面的导入错误创建INSTALLED_APPS数据库：

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

这里是我的settings.py：

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

什么是你的'DJANGO_SETTINGS_MODULE'的确切值，你在哪里把它设置？ –

'DJANGO_SETTINGS_MODULE = C：\ Users \ mspringer \ Google Drive \ Python \ Django \ mysite \ mysite \ settings.py' 它是在我的环境变量 – Mike49

的错误是没有什么实际的INSTALLED_APPS;如果您注意到，错误发生在mod = importlib.import_module(self.SETTINGS_MODULE)上，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需要是点状Python路径，而不是文件系统路径。我最适合你需要的猜测是：

DJANGO_SETTINGS_MODULE="mysite.mysite.settings"

这改正了它。我不得不更改'DJANGO_SETTINGS_MODULE =“mysite.settings”' – Mike49

一个额外的评论，事实证明，我甚至不需要在环境变量中定义'DJANGO_SETTINGS_MODULE'。 manage.py模块将其设置为：'os.environ.setdefault（“DJANGO_SETTINGS_MODULE”，“mysite.settings”）' – Mike49

ImportError: Import by filename is not supported.

看起来您正在尝试导入应用程序并指定文件名而不是名称。你能发布settings.py吗？你必须写这样的事：

INSTALLED_APPS = (

... snip ... 

    'polls', 
)

，而不是像这样：

INSTALLED_APPS = (

... snip ... 

    'polls.py', 
)

中定义的我没有改变Django构建的默认值： INSTALLED_APPS =（ 'django.contrib.admin'， 'django.contrib.auth'， 'django.contrib.contenttypes'， 'django.contrib.sessions'， 'django.contrib.messages'， ' django.contrib.staticfiles'，）' – Mike49

hm，好的。在教程的哪一点你卡住了？ – aronadaal

在[此步骤]（https://docs.djangoproject.com/zh/1/8/intro/tutorial01/）“这些应用程序默认情况下包含在常见情况下方便使用某些应用程序使用至少有一个数据库表，所以我们需要在数据库中创建表，然后才能使用它们。运行以下命令：“ '$ python manage.py migrate' – Mike49
