ImportError：无法导入设置

Question

I am trying to develop an sample project in Django and getting errors when I run the syncdb command.

This is how my project structure looks like:

/Users/django_demo/godjango/bookings:

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

And my manage.py file is as follows:

#!/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)

And my PYTHONPATH and DJANGO_SETTINGS_MODULE are set as below

$echo $DJANGO_SETTINGS_MODULE
bookings.settings

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

And my WSGI.py file looks like below:

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

When I run the python manage.py syncdb command, I am getting the following error.

Traceback (most recent call last):

    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

Could someone suggest what I am missing?

Answer 1

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

So, is your path /Users/django_demo/godjango/bookings within the python-sys.path?

Check it in your shell with:

$ python

>>> import sys
>>> for path in sys.path: print path

If not - you need to add it or simply move your bookings app into one of the paths represented in your sys.path

Answer 2

Modify your wsgi.py file from

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

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()

Answer 3

The significant part of the traceback here is right at the very end. It says "No module named unipath". You've referred to that somewhere in your code, but you don't seem to have it in your project - it's not part of the standard library, so you'll need to install it somewhere that Python can see it.

Answer 4

Alternatively, you can even pass the settings path at run time like so:

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

This should override the environment variable (DJANGO_SETTINGS_MODULE)

Answer 5

Review hour /etc/apache2/httpd.conf file; you must include the WSGIPythonPath directive, to indicate the folder which contains your Django project (manage.py file), like:

WSGIPythonPath /home/user/Projects/Django/MyProject

also if you used some weird port in your VirtualHost, specify if for listening:

Listen 90

Hope this helps somebody

Answer 6

ImportError: Could not import settings 'settings' (Is it on sys.path? Is there an import error in the settings file?): No module named setting

就我而言，我正在使用__init__.py导入其他文件，但其中存在错误，因此设置可能实际上存在但存在缺陷。
