Question

我在Windows 7 - 64位上安装了Canopy 1.5.2。我执行了Enthought web page中描述的所有步骤，但Canopy GUI无法启动。我意识到这个问题与Qt有关，因为不需要这些程序的应用程序（如Mayavi，Pylab等）可以很好地工作。当我试着跑，p.e。 ipython qtconsole，控制台上显示以下内容：

D:\Enthought\Canopy\User\Scripts>ipython qtconsole
Error in sys.excepthook:

    old_excepthook(exctype, value, tb)

Original exception was:

，但是当我开始ipython notebook时一切正常。我还使用enpkg更新了所有包。我感谢任何帮助。提前谢谢。

更新：我设置了set QT_API = pyqt，现在我可以运行ipython qtconsole和ipython qtconsole -pylab=qt了。但我仍然无法运行Canopy GUI（代码编辑器或包管理器）。

通常这个错误意味着PySide无法找到Qt DLL，或者它找到的那些不是正确的版本而且没有一些预期的符号。在PATH的某个地方，你的系统上还有其他一套Qt库吗？您可以使用Dependency Walker工具检查PySide * .pyd文件，以查看它正在搜索的其他DLL及其加载的DLL。
