Python Attribute Error when running script: type object 'BaseCommand' has no attribute 'option_list'

问题

I saw this post on how to run a python script from django: http://www.djangotutsme.com/how-to-run-python-script-from-django/
I tried the example but get the following error when running python manage.py runscript myscript. I have Python 2.7, Django 1.10 and django extensions 1.6.1 installed.

Traceback (most recent call last):
  File "manage.py", line 10, in <module>

    **option_list = BaseCommand.option_list + (
AttributeError: type object 'BaseCommand' has no attribute 'option_list'**

Any idea what the problem is? Is this a bug in django?

回答1:

BaseCommand.option_list is deprecated in Django 1.8 and removed in Django 1.10. It looks like Django-extensions has been updated, but there hasn't been a new release since then.

You could try installing django-extensions from the master branch, but it would be a better idea to use the latest release of Django, currently 1.9.2. Django 1.10 has not been released yet, and is still under development.
