ImportError：无法导入设置

我正在尝试在Django中开发示例项目，并且在运行syncdb命令时遇到错误。

这是我的项目结构的样子：

/ 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

有人可以建议我缺少什么吗？

回答：

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

那么，你的路径是否/Users/django_demo/godjango/bookings在python-sys.path中？

使用以下命令在你的外壳中检查它：

如果不是-你需要添加它或将你的bookings应用程序移动到你所表示的路径之一中sys.path
