Python属性运行脚本时出错：type object'BaseCommand'没有属性'option_list' [英] Python Attribute Error when running script: type object 'BaseCommand' has no attribute 'option_list'

问题描述

我看到这篇关于如何从django运行python脚本的帖子： http://www.djangotutsme.com/how-to-run-python-script-from-django/

我尝试了这个例子，但运行 python manage.py runscript myscript 。
我有Python 2.7，Django 1.10和django扩展1.6.1安装。

 追溯（最近的呼叫最后） ：

任何想法是什么问题是django中的一个错误？
解决方案
   BaseCommand.option_list  在Django 1.8中被弃用，在Django 1.10中被删除，看起来像Django扩展已更新，但自那以后还没有发布新的版本。
 
 
 
您可以尝试从主分支安装django扩展，但使用最新版本的Django（目前为1.9.2）将是一个更好的主意。 
 Django 1.10尚未发布，目前仍在开发中。
 
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):

    **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?
解决方案
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.
