Relative imports require the 'package' argument

问题

I want to use Sphinx so it can automatically generate a pydoc for my python code but I'm getting an error. What an I doing wrong?

conf.py sphinx config file

import sys
import os
from django.conf import settings
os.environ['DJANGO_SETTINGS_MODULE'] = '../cloud_server.settings'

sys.path.insert(0, os.path.abspath('../cloud_server/cloud_api'))

views.py django file

from django.contrib.auth.models import User, Group
from rest_framework import viewsets
from cloud_api.serializers import UserSerializer, GroupSerializer


class UserViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = User.objects.all()
    serializer_class = UserSerializer


class GroupViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = Group.objects.all()
    serializer_class = GroupSerializer

Typeerror error thrown when I'm trying to make the html file.

回答1:

DJANGO_SETTINGS_MODULE is expected to be a Python module identifier, not a filesystem path. Looking at the django/conf/__init__py file, it seems that a relative path to your settings module won't work there. You will need to move it below a directory listed in your sys.path, or you should add a parent directory to your sys.path and reference your settings module from there.

I came to this question via Google, so I'll answer what helped me (not directly related to the question).

I use importlib to dynamically import sub-packages given by a string.

import importlib
module_name = 'subpackage.i.import'
special_module = importlib.import_module(module_name, package=None)

This simply has to be adjusted to

import importlib
module_name = 'subpackage.i.import'
special_module = importlib.import_module(module_name, package='my_current_pkg)

回答3:

may be the settings you set in uwsgi.py is not correct
the settings path in uwsgi.py(XXXX is in the same dir as uwsgi.py):

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "XXXX.settings")

回答4:

You can also get this error simply if you have a typo in where you're specifying your settings file name.
