iPython Notebook in Windows - Error on Startup

问题

I am trying desperately to get ipython notebook to work in a windows environment. I installed Continuum IO's Anaconda, a scientific distribution of python. I want to use ipython notebook, but get the following error. ipython in the terminal works fine. Any thoughts?

UPDATE: As asked for below, here is the output from sys.path on my system.

['',
 'C:\\Anaconda\\scripts',
 'C:\\Anaconda\\lib\\site-packages\\distribute-0.6.45-py2.7.egg',
 'C:\\Anaconda',
 'C:\\Users\\btibert\\ C:\\Anaconda\\Scripts',
 'C:\\Anaconda\\python27.zip',
 'C:\\Anaconda\\DLLs',
 'C:\\Anaconda\\lib',
 'C:\\Anaconda\\lib\\plat-win',
 'C:\\Anaconda\\lib\\lib-tk',
 'C:\\Users\\btibert\\AppData\\Roaming\\Python\\Python27\\site-packages',
 'C:\\Users\\btibert\\AppData\\Roaming\\Python\\Python27\\site-packages\\Orange\\orng',
 'C:\\Users\\btibert\\AppData\\Roaming\\Python\\Python27\\site-packages\\setuptools-0.6c11-py2.7.egg-info',
 'C:\\Anaconda\\lib\\site-packages',
 'C:\\Anaconda\\lib\\site-packages\\PIL',
 'C:\\Anaconda\\lib\\site-packages\\win32',
 'C:\\Anaconda\\lib\\site-packages\\win32\\lib',
 'C:\\Anaconda\\lib\\site-packages\\Pythonwin',
 'C:\\Users\\btibert\\AppData\\Roaming\\Python\\Python27\\site-packages\\IPython\\extensions']

And here is the error:

回答1:

It would be helpful to know what your sys.path is. You can find that by doing:

$ ipython

In [1]: import sys

In [2]: sys.path

And then share here the output. Next, you want to check what files you have in this directory:

C:\Users\btibert\AppData\Roaming\Python\Python27\site-packages\zmq\eventloop\platform

Ideally, you'll see auto.py there, and if C:\Users\btibert\AppData\Roaming\Python\Python27\site-packages is in your sys.path then it is a mystery why it isn't working, but if that file isn't there, the directory doesn't exist, or the path to site-packages isn't in your sys.path, then those need to be resolved first.

Let us know and we can try to take it from there!

I figured out one way to attack this. I didn't really think I would have to get this level, but I completely uninstalled every single possible instance of python I could find. I

unisntalled Anaconda CE
removed every reference to python in PATH
edited my registry to clear out python data (but did leave Python folders)
Removed python from the App/Roaming path outlined above by @IanSR

Basically, I removed every possible reference to python I could find and then re-installed Anaconda CE. Voila, the Anaconda install (appears) to have worked as intended by the distributors.
