Installation of django-scheduler: $python manage.py runserver returns KeyError: u'__module__'

问题

I installed django-scheduler with pip (https://github.com/llazzaro/django-scheduler) and I edited settings.py as in the tutorial. When I run $python manage.py runserver I got this:

python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 354, in execute
    django.setup()
  File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 21, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/usr/local/lib/python2.7/dist-packages/django/apps/registry.py", line 108, in populate
    app_config.import_models(all_models)
  File "/usr/local/lib/python2.7/dist-packages/django/apps/config.py", line 202, in import_models
    self.models_module = import_module(models_module_name)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/usr/local/lib/python2.7/dist-packages/django_scheduler-0.7.5-py2.7.egg/schedule/models/__init__.py", line 1, in <module>
    from schedule.models.calendars import *
  File "/usr/local/lib/python2.7/dist-packages/django_scheduler-0.7.5-py2.7.egg/schedule/models/calendars.py", line 110, in <module>
    class Calendar(with_metaclass(ModelBase, *get_model_bases())):
  File "/usr/lib/python2.7/dist-packages/six.py", line 617, in with_metaclass
    return meta("NewBase", bases, {})
  File "/usr/local/lib/python2.7/dist-packages/django/db/models/base.py", line 71, in __new__
    module = attrs.pop('__module__')
KeyError: u'__module__'

I tried to reinstall Python (2.7), Django (1.7) and the app. I need a calendar app to my project and this seems the most complete.

Thanks.

回答1:

I had this same issue. It turned out to be a problem with the version of python's six I had installed. I was using six version 1.6.1, and when I upgraded to version 1.9.0 it took care of this error. Run:

pip-2.7 install --upgrade six

回答2:

run this script using djago-getversions.py

import pip
 installed_packages = pip.get_installed_distributions()
 installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
 for i in installed_packages])
  print(installed_packages_list)
