我喜欢 ipython，我现在正在学习 python 来代替 R 进行数据分析。但是在提示时我收到以下消息：

$ ipython --qtconsole
Traceback (most recent call last):
  File "/Library/Frameworks/EPD64.framework/Versions/Current/bin/ipython", line 5, in <module>
    from IPython.frontend.terminal.ipapp import launch_new_instance

    from IPython.utils.traitlets import (
ImportError: cannot import name CRegExp

Ipython 一周前工作得很好，现在我得到了这个错误。任何人都可以提出可能导致这种情况的原因吗？

正如@favoretti 提到的，这是utils.traitlets.

我建议升级到 EPD 7.3，看看是否能解决问题。我觉得不好建议“在地毯下刷它”解决方案，但如果你刚开始使用 python 钻研 IPython 的内部可能会有点头疼。
