Is there a way to enable autocompletion for PyQt5 with Eclipse Kepler and PyDev 2.8?
Question: it seems I can't find a way to enable autocompletion for PyQt5 in Eclipse
using PyDev 2.8. I'm running Mac OS 10.9 Mavericks.

While installing PyQt5 I noticed that there weren't '.py' modules installed in
the default library paths for PyQt5 but only '.sip' files. Can this be the
cause of the problem? If yes, does exist a workaround?

Example:

    
    
    from PyQt5.QtCore import *
    QA #here I'd expect QApplication appear as suggestion but it doesn't
    

Note: this is just an example. Autocompletion does not show any of the
modules, classes, method, functions or whatever from PyQt5.

The following is the value of the PYTHONPATH variable:

    
    
    macbookpro:~ giovanni$ echo $PYTHONPATH
    :/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
    

And here the listing of files and dirs there:

    
    
    macbookpro:site-packages giovanni$ ls -haltR

Answer: It seems things are in place... PyDev 2.8.x did have some issues on setting
the PYTHONPATH when things changed, so, ideally, please try the nightly build
(see: <http://pydev.org/download.html> for details on getting it) and see if
it fixes things for you.

Note that on PyDev 3.x you need to point Eclipse to use a Java 7 JVM (some
users seem to have issues on making Eclipse use it the proper java vm,
especially on Mac OS -- if you have this problem, maybe you can check LiClipse
0.9.0 -- which is mostly a distribution of PyDev standalone + some other
niceties + a way to directly support PyDev -- and it has PyDev 3 builtin --
otherwise, take a look at <http://stackoverflow.com/a/20477000/110451> for
instructions on how to configure it).
