Ipython won't start on W7

[tala75]

Hi everybody,
Excuse me if this has allready been answered, but I couldn't find anything so :
I've installed Python 3, 64B on windiws 7 and it runs fine.

I've then followed the steps to install iPython (Distribute, then pyreadline (from the installer this one), then I've installed iPython (from the exe installer also : ipython-0.13.py3-win-amd64.exe).

But when I start iPython it stops after displayind the following messages. What did I wrong ?
(note : the syntax error mark bellow points to the third final quote of the unicode string above it)

It looks like you have a bad install of pyreadline (i.e. one that is not meant for python3). Which version did you install?

Try using version 2.0-dev1 from https://launchpad.net/pyreadline/+download

[tala75]

You are right, I installed the "pyreadline-1.7.1" version (from PyPi).
I've downloaded and intalled the 2.0-dev1 you mentionned, and IPython starts perfectly.

Thank you for your help,
Olivier.
