@jxingm How did you install PyQt? Are there any other warnings/errors?

[jxingm]

@jsulm I followed this:
(1) install sip
sudo python configure.py
make
sudo make install
(2) install some packages
sudo apt-get install libxext6 libxext-dev libqt4-dev libqt4-gui libqt4-sql qt4-dev-tools qt4-doc qt4-designer qt4-qtconfig
(3) install pyqt4
sudo python configure.py
sudo make
sudo make install

After these instructions,I copied '/usr/lib/python2.7/dist-packages/PyQT4' and '/usr/lib/python2.7/dist-packages/sip.so' to my virualenv
python2.7 .
I can import PyQt4,but when I tried to run ,got the error above ,no other errors.

If you do not get the answer you need here, suggest you join the "PyQt mailing list" (https://riverbankcomputing.com/mailman/listinfo/pyqt or similar) and ask there.

Hi,

Why not use the PyQt4 provided by your distribution ?

@SGaist Hi, I'm not sure what you mean... Do you mean the other ways to install PyQt4 ? I have tried pip and .whl ,neither worked.
Can you help?

[jxingm]

@JonB Ok,I will see.Thanks.

Yes there is: use your distribution package manager aka apt

apt-cache search pyqt4
