ipython import ipython import error

sudo pip install ipython --upgrade # 升级

版本兼容性问题，升级到最新版本的ipython 后，会报错

from pickleshare import PickleShareDB
  File "/usr/local/lib/python2.7/dist-packages/pickleshare.py", line 40, in <module>
    from path import Path
ImportError: No module named path

解决方法，使用低版本的path.py

~$ sudo pip install -I path.py==7.7.1
Downloading/unpacking path.py==7.7.1

搞定！
