我需要帮助来弄清楚为什么会出现此错误：
[everything fine until here...]

我在 Ubuntu 14.04 的 virtualenv 中安装 PyQt 5.4。我已经安装了 SIP（版本 4.16.8，which sip返回 virtualenv 中的那个），并且在配置运行期间似乎一切都很好：
python configure.py --qmake /home/hugo/Qt/5.4/gcc_64/bin/qmake
输出（除其他外）：
Qt v5.4.2 (Open Source) is being used.
The qmake executable is /home/hugo/Qt/5.4/gcc_64/bin/qmake.
Qt is built as a shared library.
SIP 4.16.8 is being used.
The sip executable is /home/hugo/Desktop/my_pyqt_examples/venv/bin/sip.
These PyQt5 modules will be built: QtCore, QtGui, QtHelp, QtMultimedia,
QtMultimediaWidgets, QtNetwork, QtOpenGL, QtPrintSupport, QtQml, QtQuick,
QtSql, QtSvg, QtTest, QtWebKit, QtWebKitWidgets, QtWidgets, QtXml,
QtXmlPatterns, QtDesigner, QtDBus, _QOpenGLFunctions_2_0,
_QOpenGLFunctions_2_1, _QOpenGLFunctions_4_1_Core, QtSensors, QtSerialPort,
QtX11Extras, QtBluetooth, QtPositioning, QtQuickWidgets, QtWebSockets, Enginio,
QtWebChannel, QtWebEngineWidgets.
The PyQt5 Python package will be installed in
/home/hugo/Desktop/my_pyqt_examples/venv/lib/python3.4/site-packages
告诉我是否需要更多信息。我还尝试在 Ubuntu 存储库的 qt 版本上安装 PyQt 5.2，但我遇到了同样的错误。我能做些什么？
编辑：
我改用克服了这个问题sip 4.16.7。但我认为这不是解决方案，所以如果有人知道为什么最新版本不起作用，请详细说明。
