Question

我正在使用IPython 0.13.2，我想在QT控制台上试用IPython。但是，在PySide上执行easy_install后，它安装了1.2.0版本。做ipython qtconsole仍然会出现同样的错误：

    File "c:\python27\lib\site-packages\IPython\config\application.py", line 352, in initialize_subcommand
    subapp = import_item(subapp)
  File "c:\python27\lib\site-packages\IPython\utils\importstring.py", line 40, in import_item
    module = __import__(package,fromlist=[obj])
  File "c:\python27\lib\site-packages\IPython\frontend\qt\console\qtconsoleapp.py", line 56, in <module>
    from IPython.external.qt import QtCore, QtGui
  File "c:\python27\lib\site-packages\IPython\external\qt.py", line 57, in <module>
    raise ImportError('Cannot import PySide >= 1.0.3 or PyQt4 >= 4.7')
ImportError: Cannot import PySide >= 1.0.3 or PyQt4 >= 4.7

然而，当我启动IPython并尝试导入PySide时，它看起来很好：

Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)]
Type "copyright", "credits" or "license" for more information.

In [1]: import PySide

In [2]: PySide.__version__
Out[2]: '1.2.0'

是什么给出的？我在Windows XP上，使用Console2（在IPython网站上推荐），但也尝试使用相同结果的命令提示符。

发现问题：

我需要先从Python 2.7.3升级到Python 2.7.5，因为PySide 1.2是用2.7.5构建的。

之后，我只需要在pygments上做easy_install 然后ipython qtconsole工作正常！

ipython没有认识到安装了PySide？
