As the offical pyqt5-installation in the ubuntu repositories seem to lack support for QtQuick, I tried to install pyqt5 from source. The installation itself seems to work correctly, but when running a python script that uses PyQt5, python complains that it cannot find that PyQt.
After building sip 4.15.5, I downloaded PyQt5.2. It should be compatible to my version of Qt (output of qmake --version
):
QMake version 3.0
Using Qt version 5.2.0 in /opt/qt5.1.1/5.2.0/gcc_64/lib
I ran
The output of configure.py of pyqt can be found here: https://gist.github.com/Mitmischer/8677889 .
The installation output of pyqt can be found here: https://gist.github.com/Mitmischer/8677780 .
After sudo make install
, I can see a folder PyQt5
in /usr/lib/python3.3/site-packages
which is quite nice. However, if I run cat PyQt5/__init__.py
, there is no actual code inside:

Yep, that's all what is inside that file. I don't know whether it's supposed to be that way, but it looks strange to me. Furthermore (ls PyQt5
):
__init__.py QtCore.so QtGui.so QtMultimediaWidgets.so QtPositioning.so QtQuick.so Qt.so QtTest.so QtX11Extras.so
_QOpenGLFunctions_2_0.so QtDBus.so QtHelp.so QtNetwork.so QtPrintSupport.so QtSensors.so QtSql.so QtWebKit.so QtXmlPatterns.so
QtBluetooth.so QtDesigner.so QtMultimedia.so QtOpenGL.so QtQml.so QtSerialPort.so QtSvg.so QtWidgets.so uic/
Doesn't look that pythonic.
As suggested elsewhere, I (hopefully) set my pythonpath appropriately:
> echo $PYTHONPATH
/usr/lib/python3.3/site-packages/
Now, if I start an interactive python3.3
-session (or a script), PyQt5 cannot be found:
Python 3.3.2+ (default, Oct 9 2013, 14:50:09)
[GCC 4.8.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt5 import *
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'PyQt5'
>>>
Has anyone else tried to install PyQt5 from source? What can I do to make PyQt work?
