--system-site-packages オプションを使用して、Ubuntu 12.10 で virtualev (~/ENV) を作成します。ここでは、pip sphynx と pyzmq (spyder のインストールに必要) を使用してインストールし、次に spyder 自体と ipython (逆方向でも試しました) を使用してインストールします注文）。Spyder は Ipython がなくても正常に動作しますが、Ipython をインストールした後に実行しようとすると、ImportError が発生します。

from spyderlib import spyderコンソールから試すと、同じエラーが発生します。ただし、次の行 (同じコンソール、エラーの直後) で次のようにします。
from IPython.frontend.qt.console.rich_ipython_widget import RichIPythonWidget
...それはうまくいきます！

Ipython は正常に動作し、qtconsole も動作します。
