Access PyQt4 In virtual env

gistfile1.md

Install PyQt4 access it from a virtual env

Just install it system wide, see PyQt4 installation procedure

SIP Installation. Download the .tar file then uncompress

tar -xzf

then configure it with

python configure.py --incdir=~/.virtualenv/<virtualenvironmentname>/include/python2.7
make 
sudo make install

The path after the configure.py is so SIP links to any virtual enviroments you specifiy. PyQt4 Can then use SIp in these virtual envs.

PYQT4 Ubuntu

sudo apt-get install python-qt4

Put the following in the file ~.virtualenvs/postactivate
This links the PyQt4 library to all virtualenvs when they are activated.

#!/usr/bin/env bash
# This hook is sourced after every virtualenv is activated.

#set -e # abort after any errors
#set -u # exit after accessing an undefined variable
