为什么IPython QtConsole不启动？

我已经安装IPython中与在安装页面描述也已经安装了自制（QT，PyQt的，和SIP）的qtconsole依赖“画中画安装IPython的[全部]”。然而，当我尝试从“IPython中qtconsole”端启动qtconsole，我收到以下错误信息：为什么IPython QtConsole不启动？

这是怎么回事错在这里？任何帮助将不胜感激。

注：类似于这里发出（http://stackoverflow.com/questions/25752315/error-loading-ipython-qtconsole?rq=1）;该线程，以及下面的评论（！感谢击昏），建议增加 “出口PYTHONPATH =在/ usr/local/lib目录/ python2.7/site-packages中：$ PYTHONPATH” 对.bash_profile解决了这个问题。 – thereislight 2014-10-12 03:45:11

错误消息说你没有安装既不PyQt4的也不PySide> = 1.0.3。您应该检查正确安装的两个软件包中的一个。你说你安装pyqt，但你有错误。也许，它是pyqt版本3. PyQt版本4具有不同的名称，如PyQt4。在这种情况下，你应该安装pyqt4。

我查PyQt的版本与BREW ls - 版本，似乎pyqt，qt和sip都是最新的。版本号是：pyqt 4.11.1; qt 4.8.6;啜饮4.16.3。也许我需要手动导入pyqt？或者，也许我的文件路径在哪里搞砸了？我会尝试重新安装pyqt，qt和sip;我们会看看是否有效。 – thereislight 2014-10-12 03:22:11

你检查你更新PYTHONPATH，如 “出口PYTHONPATH =在/ usr/local/lib目录/ python2.7/site-packages中：$ PYTHONPATH ”？ Homebrew通常需要这样做。另一方面，您也可以尝试使用自制软件安装ipython，而不是点子。 – Jihun 2014-10-12 03:27:54

啊，是的，我只是做到了这一点，它运作得非常好！非常感谢。顺便说一句，你是否碰巧知道为什么自制软件通常要求/为什么这条线使它工作？ – thereislight 2014-10-12 03:32:46
