Pyzmq error in IPython laptop

Question

I am trying to run an IPython laptop in Vista. I believe that I have installed all the necessary dependencies (listed here ) with easy_install. IPython is working fine. But when I try to start the IPython laptop, everything starts fine, but then the kernel dies when I try to do something. I get the following confusing error:

Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Python27\lib\site-packages\ipython-0.11-py2.7.egg\IPython\zmq\__init__.py", line 25, in <module> minimum_pyzmq_version, pyzmq_version)) ImportError: IPython.zmq requires pyzmq >= 2.1.4, but you have 2.1.11 

2.1.11> = 2.1.4, so I'm not sure what the problem is. 2.1.11 is the latest version of pyzmq ( here is the project page).

[Update: Thanks @ThomasK. I already ran IPython 0.12, but I ran easy_install --upgrade on both IPython and pyzmg and fixed it.]

Answer 1

This bug was fixed in IPython 0.12, so you will need to update it. Anyway, you need 0.12 to run the laptop.

If you have problems updating, try deleting the folder in which IPython 0.11 is installed, and then reinstalling using easy_install.
