Installing iPython: "ImportError cannot import name path"?
Question:
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 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?
Answers:
It appears that pickleshare is in package IPython.utils. Try tying
from IPython.utils.pickleshare import PickleShareDB
Similarly, path is in IPython.external. Try typing
from IPython.external.path import path as Path
In either case, I would check if following files exist.
"/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/utils/pickleshare.py"
"/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/external/path/_path.py"
All this points to the fact that probably your IPython/notebook version is old. A couple of solutions would be
1) Try editing files in site-packages and changing import lines to
from IPython.external.path import path as Path
from IPython.utils.pickleshare import PickleShareDB
But that’s kind of risky, who knows what else might fail.
Otherwise, try upgrading ipython/notebook
pip install ipython --upgrade
pip install "ipython[notebook]" --upgrade
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
I had similar issues and rolling back to an earlier version of path.py did not not help. I uninstalled the package and then IPython Notebook worked.
pip uninstall -y path.py
I received this error while trying to import matplotlib on Windows 10. My problem was that matplotlib needed an update. I just ran the following code:
python -m pip install matplotlib
or:
conda install matplotlib
My guess is that this can be applied to IPython.
This works for me, use :
from pathlib import Path
import Path (not path – It should be "UPPER CASE" P and not "lower case" p)
