加载ipython qtconsole时出错

问题描述 投票：4回答：3

我需要一些建议。我安装了ipython（sudo pip install ipython [all]）

我有python 2.7，mac osx 10.9 64bits。

我正在尝试午餐qtconsole

camilo-mbp:mvc cami$ ipython qtconsole

我已经完成以下命令将pyQt4安装为True并且正常工作

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

现在，我想安装pyside，但我有一些错误：

因为我知道，cmake不是python包。它是一个构建工具。所以，你所要做的就是安装它。你可以从这里得到它：CMake site

此外，您应该检查Apple开发工具是否已经拥有cmake。

问题陈述Qtconsole导入错误或冲突。

这是我收到的确切错误消息

File "uikit/ipython.py", line 5, in <module>
ImportError: No module named qt.console.rich_ipython_widget
[28603] Failed to execute script bosetap

Currently-imported Qt library: 'pyqt'
PyQt4 installed: False
PyQt5 installed: False
PySide >= 1.0.3 installed: False
PySide2 installed: False
Tried to load: ['pyqt']

你可以深入了解uikit / ipython.py并看到有一个try catch块围绕导入新旧库及以下内容。

QT_API = os.environ.get('QT_API', None)
if QT_API not in [QT_API_PYSIDE, QT_API_PYSIDE2, QT_API_PYQT, QT_API_PYQT5, None]:
raise RuntimeError("Invalid Qt API %r, valid values are: %r, %r, %r, %r" %
(QT_API, QT_API_PYSIDE, QT_API_PYSIDE2, QT_API_PYQT, QT_API_PYQT5))
if QT_API is None:
api_opts = [QT_API_PYQT5, QT_API_PYSIDE2, QT_API_PYSIDE, QT_API_PYQT]
else:
api_opts = [QT_API]

步骤1）我开始在python提示下手动运行东西，我确信自己已正确安装qt.console。如果你发现你不能这样做。安装缺少的模块。

pip install qtconsole

步骤2）如果您使用pyqt4，请确保在pyinstaller规范文件中排除pyqt5，pyside和pyside2模块。它可能看起来像这样。这在分析部分

excludes=['pyqtgraph.graphicsItems.PlotItem.plotConfigTemplate_pyqt5',
                'pyqtgraph.graphicsItems.PlotItem.plotConfigTemplate_pyqt5',
                'pyqtgraph.graphicsItems.ViewBox.axisCtrlTemplate_pyqt5',
                'pyqtgraph.GraphicsScene.exportDialogTemplate_pyqt5',
                'PyQt5',' PyQt5.QtCore','PyQt5.QtGui','PyQt5.QtPrintSupport',
                'PyQt5.QtSvg','PySide','PySide2'],

这可能是矫枉过正的。一旦我开始工作，我不想触摸它。优化留给读者练习。

Step3）我将首先告诉你解决方案然后如何到达那里。问题是pyinstaller将我的pyqt4可执行文件放在包中的顶层。 Qtconsole正在PyQt4目录中查找它们。以下是spec文件的exe部分。

a.binaries + [('PyQt4/QtCore.so','/usr/lib/python2.7/dist-packages
  PyQt/QtCore.so','BINARY'), ('PyQt4/QtGui.so','/usr/lib/python2.7/dist-packages
/PyQt4/QtGui.so','BINARY'), ('PyQt4/QtOpenGL.so','/usr/lib/python2.7/dist-packages 
/PyQt4/QtOpenGL.so','BINARY'), ('PyQt4/QtSvg.so','/usr/lib/python2.7/dist-packages
/PyQt4/QtSvg.so','BINARY'), ('PyQt4/QtTest.so','/usr/lib/python2.7/dist-packages
/PyQt4/QtTest.so','BINARY'), ('PyQt4/QtXml.so','/usr/lib/python2.7/dist-packages

/py QT4/QT XML.so,'binary) ],

所以，关于这个解决方案的不好的部分是我们现在得到警告，我们在两个地方有相同的可执行文件。优化留给读者练习。老实说，我还没弄清楚如何解决这个问题。所以，如果你这样做......很高兴收到你的来信。这就是我进入第3步的方式。我认为这部分很重要。我将此添加到我的spec文件中仅用于开发，而不是用于客户的包。开发包的问题是它无法运行，然后tmp /目录将自行删除。我看不出有什么问题。我知道我安装了pyqt4并且应用程序是手动运行的。这非常令人沮丧。因此，如果您对规范文件执行以下操作，您将获得一个内置目录而不是可执行文件。该目录保持不变，您可以在内部达到峰值，看看发生了什么。然后，你有武装和危险，以启用解决方案。然后，当您使用它时，您可以将其还原为您的客户开发可执行文件。

  exe = EXE(pyz,
              a.scripts,
             [],
              exclude_binaries=True,
              name='bosetap',
              debug=False,
              bootloader_ignore_signals=False,
              strip=False,
              upx=True,
              console=True )

    coll = COLLECT(exe,
                   a.binaries,
                   a.zipfiles,
                   a.datas,
                   strip=False,
                   upx=True,
                   name='bosetap')

特别感谢我的老板，因为我撞了这个头一个星期。快乐的小道。
