没有名为traitlets.config.application的模块

Question

我ipython在Ubuntu 14.04上安装了apt-get install ipython,我的python版本是2.7.6.当我ipython在控制台中运行时,我遇到了这个错误,我在任何网站上都找不到任何类似的问题.有人能帮我吗？

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

Answer 1

正如@ user3682792所说的那样

sudo pip install traitlets

解决了这个问题.谢谢!
