See this thread, worked for me: http://stackoverflow.com/questions/33446131/pyqt5-error-during-python3-configure-py-fatal-error-qgeolocation-h-file-no/33460342#33460342

That's right, after the configure step the file has gone. Is there a way to keep it there, i.e. to tell configure.py to not clean it out?

Everything pretty much installs fine and then I get this error when trying to import any Qt module in python (from pyqt5 import QtGui):

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/QtGui.so, 2): Library not loaded: @rpath/QtGui.framework/Versions/5/QtGui
  Referenced from: /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/PyQt5/QtGui.so
  Reason: image not found

I have reinstalled Qt and PyQt5 and I did have XCode installed and accepted

edit: Solution was to give up on trying to build it from source and get it from homebrew instead

note that you might have to include --pyuic_interpreter to point to the right python executable if you are using virtualenv. pyuic5 doesn't work without this, in my setup.

How to fix it please?

I apparently am missing the QtWebKit and QtWebKitWidgest with the latest Qt5.6.0 and PyQt5.5.1, and I got the following error when I tried to run spyder

How should I install the QtWebKitWidgest?

Thank you for this. Extremely helpful. I originally had tried to do this without a virtual environment, but after setting up a virtual environment and setting Python to version 3.5 in that environment, it worked.

Also, @TPeterW, apparently QtWebKit was deprecated. See http://stackoverflow.com/questions/37876987/cannot-import-qtwebkitwidgets-in-pyqt5.

@hantsaniala did you solve your problem about :
Error: Failed to determine the detail of your Qt installation. Try again using the --verbose flag to see more detail about the problem.
I have the same issue. Please, anyone could help me ?
Anyway, what is the "Verbose flag ?"
