Error while starting new IPython console in Spyder

Question

While I was training a neural network with Pybrain, my computer crashed and I had to reboot it. Now Spyder, Python, IPython seem to work fine, however, when trying to open a new IPython console in Spyder, I get the following error:

Error in sitecustomize; set PYTHONVERBOSE for traceback:
TypeError: 'NoneType' object is not callable
Traceback (most recent call last):

__version__ = pkg_resources.require('path.py')[0].version
TypeError: 'NoneType' object is not callable

The error does not seem to interfere with the execution of Python scripts however I am wondering if I accidentally messed something up. I searched the internet but found nothing that could explain this error. I am using Python 3.4.3 64 bit with the Anaconda 2.3.0 distribution.

Answer 1

conda update qt pyqt

conda update spyder

pip install -U spyder

This worked for me

Answer 2

I have the same problem. and setuptools did not fix my error.

finally, run

conda update path.py

fix my error. You could check this link: https://github.com/spyder-ide/spyder/issues/2679

Answer 3

The accepted answer is correct in that it is a setup tools problem, but I couldn't use pip install --upgrade --force setuptools, that complained about not being able to find easy-install.pth

Instead I was able to upgrade setuptools using easy-install itself with: easy_install --upgrade setuptools, hope that helps someone who was stuck like me.

Answer 4

Either upgrade setuptools or try pip install --upgrade --force setuptools fixed it. Either one or the other should fix the problem.
