Python/Django shell won't start
提问by danpalmer
One of the great features of Django is that you can open a python interpreter set-up for use with your project. This can be used to analyse objects in a database and allows any python commands to be executed on your project. I find it essential for Django development. It is invoked in the project directory using this command:
Django 的一大特色是您可以打开 Python 解释器设置以用于您的项目。这可用于分析数据库中的对象，并允许在您的项目上执行任何 python 命令。我发现它对 Django 开发至关重要。使用以下命令在项目目录中调用它：
$ python manage.py shell
I have just started developing a new project and for some reason the shell does not work. I have had a look online for the error and not found anything. I would greatly appreciate any help on this error:
我刚刚开始开发一个新项目，由于某种原因，shell 不起作用。我在网上查看了错误，但没有发现任何问题。我将不胜感激对此错误的任何帮助：

shell = IPython.Shell.IPShell(argv=[])
AttributeError: 'module' object has no attribute 'Shell'
Thanks in advance for your help!
在此先感谢您的帮助！

It seems like IPython is installed wrongly somehow. Try starting the shell with:
似乎 IPython 以某种方式安装错误。尝试使用以下命令启动 shell：
./manage.py shell --plain
to start the standard Python shell, rather than IPython. If that works, then trying removing IPython completely and reinstalling it.
启动标准 Python shell，而不是 IPython。如果可行，则尝试完全删除 IPython 并重新安装它。

IPython 0.11 has a different API, for which a fix exists in the last Django versions.
IPython 0.11 有一个不同的 API，在最新的 Django 版本中存在修复。
For older Django versions, you can use IPython 0.10, which does work:
对于较旧的 Django 版本，您可以使用 IPython 0.10，它确实有效：
pip install ipython==0.10
