Python 属性错误：'；模块'；对象没有属性'；壳牌公司'；给伊皮顿

我已经在虚拟环境中的机器上安装了ipython，如下所示

pip install ipython

因此，当我从virtualenv内部以

python manage.py shell

的形式启动shell时，我看到了下面的错误

Traceback (most recent call last):

Django版本-1.2.3 venv内部的ipython版本-2.0.0

---

那么它为什么会出现以及如何避免，我以前没有经历过这种情况，我也有过同样的问题。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

如果不可能，您可以尝试安装旧版本的IPython，但我还没有测试它是否有效
