加載ipython qtconsole時出錯

Question

我需要一些建議。 我安裝了ipython（sudo pip install ipython [all]）

我有python 2.7，mac osx 10.9 64bits。

我正在嘗試午餐qtconsole

camilo-mbp:mvc cami$ ipython qtconsole

ImportError: 
Could not load requested Qt binding. Please ensure that
PyQt4 >= 4.7 or PySide >= 1.0.3 is available,

我已經完成以下命令將pyQt4安裝為True並且正常工作

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

現在，我想安裝pyside，但我有一些錯誤：

Answer 1

因為我知道，cmake不是python包。 它是一個構建工具。 所以，你所要做的就是安裝它。 你可以從這里得到它： CMake網站

此外，您應該檢查Apple開發工具是否已經擁有cmake。

Answer 3

問題陳述Qtconsole導入錯誤或沖突。

這是我收到的確切錯誤消息

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並看到有一個try catch塊圍繞導入新舊庫及以下內容。

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]

步驟1）我開始在python提示下手動運行東西，我確信自己已正確安裝qt.console。 如果你發現你不能這樣做。 安裝缺少的模塊。

pip install qtconsole

步驟2）如果您使用pyqt4，請確保在pyinstaller規范文件中排除pyqt5，pyside和pyside2模塊。 它可能看起來像這樣。 這在分析部分

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'],

這可能是矯枉過正的。 一旦我開始工作，我不想觸摸它。 優化留給讀者練習。

Step3）我將首先告訴你解決方案然后如何到達那里。 問題是pyinstaller將我的pyqt4可執行文件放在包中的頂層。 Qtconsole正在PyQt4目錄中查找它們。 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

/PyQt4/QtXml.so','BINARY'）]，

所以，關於這個解決方案的不好的部分是我們現在得到警告，我們在兩個地方有相同的可執行文件。 優化留給讀者練習。 老實說，我還沒弄清楚如何解決這個問題。 所以，如果你這樣做......很高興收到你的來信。 這就是我進入第3步的方式。我認為這部分很重要。 我將此添加到我的spec文件中僅用於開發，而不是用於客戶的包。 開發包的問題是它無法運行，然后tmp /目錄將自行刪除。 我看不出有什么問題。 我知道我安裝了pyqt4並且應用程序是手動運行的。 這非常令人沮喪。 因此，如果您對規范文件執行以下操作，您將獲得一個內置目錄而不是可執行文件。 該目錄保持不變，您可以在內部達到峰值，看看發生了什么。 然后，你有武裝和危險，以啟用解決方案。 然后，當您使用它時，您可以將其還原為您的客戶開發可執行文件。

  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')

特別感謝我的老板，因為我撞了這個頭一個星期。 快樂的小道。
