Importerror: No Module Named Pyqt4.qtcore

I've reïnstalled my ssh server, so I also need to reïnstall my Python packages. I did that, but I still get the error: ImportError: No module named PyQt4.QtCore I've already suc

Solution 1:

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

Solution 2:

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!

Solution 3:

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.

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

Solution 4:

I had the "No module named PyQt4.QtCore" error and installing the python-qt4 package fixed it only partially: I could run

fromPyQt4.QtCoreimportSIGNAL

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?

Solution 5:

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++
