我需要一些建议。我已经安装了ipython（用命令sudo pip install ipython[all]）。

我用的是python 2.7，mac osx 10.9 64位系统。

我正在尝试启动qtconsole。

camilo-mbp:mvc cami$ ipython qtconsole

我已经执行了以下命令，把pyQt4的安装状态设置为True，现在运行得很好。

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

现在，我想安装pyside，但遇到了一些错误：

问题描述：Qtconsole 导入错误或冲突。

这是我收到的确切错误信息：

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']

你可以查看 uikit/ipython.py 文件，里面有一个尝试捕获错误的代码块，主要是用来处理新旧库的导入问题。

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]

第一步）我开始在 Python 提示符下手动运行一些东西，确认 qt.console 安装正确。如果你发现自己无法这样做，那就安装缺失的模块。

可以用这个命令：pip install qtconsole

第二步）如果你使用的是 pyqt4，确保在你的 pyinstaller 规范文件中排除 pyqt5、pyside 和 pyside2 模块。它可能看起来像这样。这部分放在分析部分：

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'],

这可能有点过于复杂。一旦我让它工作了，我就不想再去碰它。优化的部分留给读者自己去做。

第三步）我先告诉你解决方案，然后再讲怎么做到。问题在于 pyinstaller 把我的 pyqt4 可执行文件放在了包的顶层，而 Qtconsole 在 PyQt4 目录中寻找它们。以下内容放在你的规范文件的 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，这个解决方案的坏处是我们现在会收到警告，提示同一个可执行文件在两个地方存在。优化的部分留给读者自己去做。老实说，我还没有找到解决这个问题的方法。如果你找到了，能告诉我就太好了。

这是我到达第三步的过程。我觉得这部分很重要。我把这个添加到我的规范文件中只是为了开发，而不是为了客户的包。开发包时遇到的问题是它无法运行，然后 tmp/ 目录会自动删除。我看不到问题出在哪里。我知道我安装了 pyqt4，并且应用程序可以手动运行，这让我很沮丧。所以，如果你对你的规范文件做以下修改，你将得到一个目录，而不是一个可执行文件。这个目录会保留，你可以查看里面发生了什么。这样，你就可以准备好解决问题了。当你让它工作后，再把这个改回去，开发出一个给客户用的可执行文件。

  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，因为我为这个问题纠结了一周。祝好运。

关于在MacOSX上构建和安装PySide的说明文档可以在这里找到：http://pyside.readthedocs.org/en/latest/building/macosx.html

我知道，cmake 不是一个 Python 包，它是一个构建工具。所以，你只需要安装它就可以了。你可以从这里下载：CMake 网站

另外，你还应该检查一下你的苹果开发工具里是否已经安装了 cmake。
