Answer 1

Under Ubuntu system, you could install it via apt-get

apt-get install python-qt4

Answer 2

OSX 10.8.2 tested:

sudo pip install SIP

got IOError: [Errno 2] No such file or directory: '/tmp/pip-build/SIP/setup.py'

It's ok then:

cd /tmp/pip-build/SIP
sudo python configure.py
make
sudo make install

download PyQt from: http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.9.6/PyQt-mac-gpl-4.9.6.tar.gz

unzip it.

cd PyQt-mac-gpl-4.9.6
sudo python configure.py
make

it will take a while, after make then:

sudo make install    

Enjoy it :)

Answer 3

As PyQt is not using setup.py it cannot be installed using pip or easy_install

Here you have a tutorial showing how to build and install PyQt for python2.7:

Update: For Ubuntu 12.04+ just use apt-get:

apt-get install python-qt4

Answer 4

Please install SIP module first,this is python and c/c++ lib tools, and PyQt4 lib

Answer 5

You can download any version of PyQt4 here for any version of Python but since you asked for python 2.7, Here is the link for the download for python 2.7:

https://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.11.4/

Answer 6

You should install PyQt4 in the Python 2.7 environment. To do this run

easy_install2.7 PyQt4

If easy_install is not installed you will need to first download and install it by running

python2.7 setup.py install
