Pyinstaller生成“RichJupyterWidget with QT4 backend”的可执行文件产生错误

Question

以下简单的example.py代码在运行时显示带有qt4后端的ipython控制台。

    import sip
    sip.setapi(u'QDate', 2)
    sip.setapi(u'QDateTime', 2)
    sip.setapi(u'QString', 2)
    sip.setapi(u'QTextStream', 2)
    sip.setapi(u'QTime', 2)
    sip.setapi(u'QUrl', 2)
    sip.setapi(u'QVariant', 2)
    from PyQt4.QtGui import *
    from qtconsole.rich_jupyter_widget import RichJupyterWidget
    from qtconsole.inprocess import QtInProcessKernelManager
    from IPython.lib import guisupport

    class IPythonWidget(RichJupyterWidget):
         def __init__(self, parent=None, **kwargs):
            super(self.__class__, self).__init__(parent)
            self.app = app = guisupport.get_app_qt4()
            self.kernel_manager = kernel_manager = QtInProcessKernelManager()
            kernel_manager.start_kernel()
            self.kernel = kernel = kernel_manager.kernel
            kernel.gui = 'qt4'
            self.kernel_client = kernel_client = kernel_manager.client()
            kernel_client.start_channels()


   if __name__ == '__main__':
        app = QApplication([])
        i = IPythonWidget()
        i.show()
        app.exec_()

但是，pyinstaller生成的可执行文件不会运行。 exe文件的调试输出如下：

尝试了很多我可以通过谷歌搜索做的事情。似乎没什么用。任何建议或帮助都非常感谢。谢谢 ！

以下信息可能会对您有所帮助

Python: 2.7.11 (From Anaconda Python Distribution)
OS: Windows 10 (x64)
PyQt: Version 4.11.4
Pyinstaller Version: 3.2-48-ga00b13d

Answer 1

我有同样的问题。在uikit\ipython.py，我在这里遇到了例外2。

try:
    from qtconsole.rich_jupyter_widget import RichJupyterWidget
    from qtconsole.inprocess import QtInProcessKernelManager
    print "here 1"

except:
    from IPython.qt.console.rich_ipython_widget import RichIPythonWidget as RichJupyterWidget
    from IPython.qt.inprocess import QtInProcessKernelManager
    print "here 2"

我必须安装qtconsole，这解决了。

pip install qtconsole

现在问题是让pyinstaller找到所有这些部分。 :-(
