我在 Ubuntu 12.10 中创建了一个 virtualev (~/ENV)，使用 --system-site-packages 选项，我使用 pip sphynx 和 pyzmq 安装（安装 spyder 所必需的），然后是 spyder 本身，然后是 ipython（也尝试反向命令）。Spyder 在没有 Ipython 的情况下可以正常工作，但是当我在安装 Ipython 后尝试运行它时，它给出了 ImportError：

zdk1g12@walrus:~$ source ENV/bin/activate
(ENV)zdk1g12@walrus:~$ spyder
Traceback (most recent call last):
  File "/home/zdk1g12/ENV/bin/spyder", line 3, in <module>

ImportError: No module named frontend.qt.console.rich_ipython_widget

from spyderlib import spyder当我从控制台尝试时，它给出了同样的错误。但是，如果在下一行（同一个控制台，就在错误之后）我这样做：

from IPython.frontend.qt.console.rich_ipython_widget import RichIPythonWidget

......它工作得很好！

一些细节：

Ipython 工作正常，qtconsole 也是如此。
