我在Ubuntu 14.04上使用spyder3（link）的开发版本，运行时出现以下错误：
File "/usr/local/lib/python2.7/dist-packages/ipykernel/__init__.py", line 2, in <module>
from .connect import *
File "/usr/local/lib/python2.7/dist-packages/ipykernel/connect.py", line 14, in <module>
from IPython.paths import get_ipython_dir
ImportError: No module named paths
我如何解决这个问题？
