[FIXED] Installing iPython: "ImportError cannot import name path"?

Issue

I'm trying to install IPython. I have run pip install ipython[notebook] without any errors, but now I get this:

$ ipython notebook
Traceback (most recent call last):
  File "/Users/me/.virtualenvs/.venv/bin/ipython", line 7, in <module>
    from IPython import start_ipython
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/__init__.py", line 48, in <module>
    from .terminal.embed import embed
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/terminal/embed.py", line 16, in <module>
    from IPython.core.interactiveshell import DummyMod
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/core/interactiveshell.py", line 31, in <module>
    from pickleshare import PickleShareDB
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/pickleshare.py", line 41, in <module>
    from path import path as Path
ImportError: cannot import name path

I have the same error if I try to run import pickleshare at a Python console, or from path import path.

What can I do to fix this?

Solution

Looks like this is a known issue, caused by a change in the path.py package. Reverting to an older version of path.py solves this :

sudo pip3 install -I path.py==7.7.1
