I had the same issue when uninstalled my Python27 and re-installed it.

I downloaded the sip-4.15.5 and PyQt-win-gpl-4.10.4 and installed/configured both of them. it still gives 'ImportError: No module named PyQt4.QtCore'. I tried to move the files/folders in Lib to make it looked 'have' but not working.

in fact, jut download the Windows 64 bit installer for a suitable Python version (my case) from http://www.riverbankcomputing.co.uk/software/pyqt/download and installed it, will do the job.

* March 2017 update *

The given link says, Binary installers for Windows are no longer provided.

See cgohlke's answer at, PyQt4 and 64-bit python.

Download the .whl file at http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4.
Use pip to install the downloaded .whl file.

I was having the same error - ImportError  No module named PyQt4 QtGui  Instead of running your python file  which uses PyQt  on the terminal as -   python file name py   Run it with sudo privileges -  sudo python file name py   This worked for me

I got the same error  when I was trying to import matplotlib pyplot  In  1   import matplotlib pyplot as plt         ImportError  No module named PyQt4 QtCore   But in my case the problem was due to a missing linux library libGL so 1  OS   Cent OS 64 bit  Python version   3 5 2    gt  locate libGL so 1   If this command returns a value  your problem could be different  so please ignore my answer  If it does not return any value and your environment is same as mine  below steps would fix your problem     gt  yum install mesa-libGL x86 64   This installs the necessary OpenGL libraries for 64 bit Cent OS     gt  locate libGL so 1  usr lib libGL so 1   Now go back to iPython and try to import  In  1   import matplotlib pyplot as plt   This time it imported successfully

Try this command to solve your problem  sudo apt install build-essential python3-dev libqt4-dev  This works for me in python3

I had the  No module named PyQt4 QtCore  error and installing the python-qt4 package fixed it only partially  I could run  from PyQt4 QtCore import SIGNAL   from a python interpreter but only without activating my virtualenv   The only solution I ve found till now to use a virtualenv is to copy the PyQt4 folder and the sip so file into my virtualenv as explained here  Is it possible to add PyQt4 PySide packages on a Virtualenv sandbox

As mentioned in the comments  you need to install the python-qt4 package - no need to recompile it yourself   sudo apt-get install python-qt4

You don t have g   installed  simple way to have all the needed build tools is to install the package build-essential   sudo apt-get install build-essential     or just the g   package   sudo apt-get install g
