python - 没有名为 traitlets.config.application 的模块

Question

我在 Ubuntu 14.04 上通过 apt-get install ipython 安装了 ipython，我的 python 版本是 2.7.6。当我在控制台中运行 ipython 时，我遇到了这个错误，而且我在任何站点上都找不到任何类似的问题。有人可以帮助我吗？

Traceback (most recent call last):
  File "/usr/local/bin/ipython", line 4, in <module>
    from IPython import start_ipython
  File "/usr/local/lib/python2.7/dist-packages/IPython/__init__.py", line 47, in <module>
    from .core.application import Application
  File "/usr/local/lib/python2.7/dist-packages/IPython/core/application.py", line 22, in <module>
    from traitlets.config.application import Application, catch_config_error
ImportError: No module named traitlets.config.application

正如@user3682792 所说，只是做

sudo pip install traitlets

为我解决了这个问题。谢谢!
