【问题描述】：

我已经在虚拟环境中的机器上安装了 ipython，如下所示

pip install ipython

Downloading/unpacking ipython
  Downloading ipython-2.0.0.tar.gz (11.9MB): 11.9MB downloaded
  Running setup.py egg_info for package ipython

Installing collected packages: ipython
  Running setup.py install for ipython

Cleaning up...

所以当我从 virtualenv 内部以 python manage.py shell 启动我的 shell 时，我看到以下错误

Traceback (most recent call last):
  File "manage.py", line 11, in <module>
    execute_manager(settings)
  File "/home/user/.virtualenvs/project/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 438, in execute_manager

AttributeError: 'module' object has no attribute 'Shell'

Django 版本 - 1.2.3 venv 内的 ipython 版本 - 2.0.0

那么为什么会出现以及如何避免，我以前没有经历过这种情况

【解决方案1】：

我遇到了同样的问题。我通过将 Django 升级到 1.2.7 解决了这个问题。

pip install --upgrade django==1.2.7

如果不可行，您可以尝试安装旧版本的 IPython，但我还没有测试过是否可行。
