导入错误：无法导入设置。

导入错误：无法导入设置。

36

我正在尝试使用Django开发一个示例项目，并在运行syncdb命令时遇到错误。

这是我的项目结构:

/Users/django_demo/godjango/bookings:

manage.py
    registration/
        forms.py
        views.py
        models.py
        urls.py
    bookings/
        settings.py
        urls.py

我的 manage.py 文件如下：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bookings.settings")
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

我的PYTHONPATH和DJANGO_SETTINGS_MODULE设置如下：

$echo $DJANGO_SETTINGS_MODULE
bookings.settings

$ echo $PYTHONPATH
/Users/django_demo/godjango/bookings

我的 WSGI.py 文件如下所示：

 import os
 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bookings.settings")
 from django.core.wsgi import get_wsgi_application
 application = get_wsgi_application()

当我运行python manage.py syncdb命令时，出现以下错误。

Traceback (most recent call last):

    self._wrapped = Settings(settings_module)

    raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'bookings.settings' (Is it on sys.path?): No module named unipath

有人能否建议我漏掉了什么?

修改您的 wsgi.py 文件，从

 import os
 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bookings.settings")
 from django.core.wsgi import get_wsgi_application
 application = get_wsgi_application()

需要翻译的内容为：

to

import os, sys    
sys.path.append(' /Users/Sreek/django_demo/godjango/bookings')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "bookings.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

这里最重要的一部分是在最后。它说：“No module named unipath”（没有名为unipath的模块）。你的代码中有引用到它，但似乎没有包含在你的工程中。因为它不是标准库的一部分，所以你需要将其安装到Python可以找到的某个地方。

或者，您甚至可以在运行时传递设置路径，如下所示：

python manage.py syncdb --settings=bookings.settings --pythonpath=/Users/django_demo/godjango/bookings

这应该覆盖环境变量 (DJANGO_SETTINGS_MODULE)

哇哦，伙计！你为我节省了pow(2, 64)个小时！谢谢你！ - user1270589

导入错误：无法导入设置“settings”（它是否在sys.path上？设置文件中是否存在导入错误？）：没有名为setting的模块

在我的情况下，我使用__init__.py来导入其他文件，并且其中出现了错误，因此设置可能实际存在但存在缺陷。

请查看 /etc/apache2/httpd.conf 文件；您必须包含 WSGIPythonPath 指令，以指示包含 Django 项目（manage.py 文件）的文件夹，例如：

WSGIPythonPath /home/user/Projects/Django/MyProject

如果您在 VirtualHost 中使用了一些奇怪的端口，请指定它进行监听：

Listen 90

希望这能帮助到某些人。

如果它在PYTHONPATH中，那么我认为这是不必要的，对吗？ - User

错误提示为ImportError: Could not import settings 'bookings.settings' (Is it on sys.path?): No module named unipath

因此，请确认你的路径 /Users/django_demo/godjango/bookings 是否在python-sys.path中？

可以在shell中使用以下命令进行检查：

如果没有 - 你需要添加它或者将你的bookings应用程序移动到sys.path中所代表的路径之一。
