Installing PyGtk in virtualenv
The trick is to manually set the correct paths and then run configure inside the virtualenv. This is quite basic, but it worked for me.
Install python-config in the virtual env and link it to python2.7-config:
pip install config
ln -s /home/PATH/TO/VIRT/bin/python-config /home/PATH/TO/VIRT/bin/python2.7-config
Install cairo in the virtual env:
wget http://cairographics.org/releases/py2cairo-1.10.0.tar.bz2
tar -xf py2cairo-1.10.0.tar.bz2
cd py2cairo-1.10.0
./waf configure --prefix=/home/PATH/TO/VIRT/
./waf build
./waf install
Install PyGTK
wget http://pypi.python.org/packages/source/P/PyGTK/pygtk-2.24.0.tar.bz2
tar -xf pygtk-2.24.0.tar.bz2
cd pygtk-2.24.0
export PKG_CONFIG_PATH=/home/PATH/TO/VIRT/lib/pkgconfig
./configure --prefix=/home/PATH/TO/VIRT/
make
make install
And that should do it. Just replace PATH/TO/VIRT/ with your own path. I'm sure someone could assist on adding the path to virtualenvwrapper?
pygtk
cannot be installed in your virtualenv from PyPI, so
pip install pygtk
will download but not install. You can go through the hoops of downloading the tar files and compiling and installing those, but if it is OK to make links to the relevant packages installed in the system then activating your virtualenv and installing ruamel.venvgtk
is enough:
pip install ruamel.venvgtk
This is a shameless plug for my own work, none of the other solutions here worked well with repeated virtualenv creation as is e.g. done by tox
.
In the setup.py
of the packages the following happens:
try:
import gtk
except ImportError:
print('--------------')
import subprocess
instdir = subprocess.check_output([
'/usr/bin/python',
'-c',
'import os, pygtk; print os.path.dirname(pygtk.__file__)',
]).strip()
for dst_base in sys.path:
if dst_base.strip():
break
for d in [
'pygtk.pth',
'pygtk.py',
'gtk-2.0',
'gobject',
'glib',
'cairo',
]:
src = os.path.join(instdir, d)
dst = os.path.join(dst_base, d)
if os.path.exists(src) and not os.path.exists(dst):
print('linking', d, 'to', dst_base)
os.symlink(src, dst)
i.e the system's python is asked where pygtk is installed (on Linux Mint 17.1 this is /usr/lib/python2.7/dist-packages
), and then links are set up to the first path (that is non-zero length) for the activated python.
I did this
sudo apt-get install python-gtk2
I found that it was already installed upon some investigation, i found out that when I create a virtual environment, it was missing some links so I came across this post: Virtualenv on Ubuntu with no site-packages.
I read it and tailored the commands provided to my setup as follows:
First I changed into my virtualenv and activated it by
source bin/activate
Then I changed into the lib/python2.7 folder inside my virtualenv:
cd lib/python2.7
I then executed the following commands.
$ ln -s /usr/lib/python2.7/dist-packages/cairo/ $ ln -s /usr/lib/python2.7/dist-packages/pygtk.py $ ln -s /usr/lib/python2.7/dist-packages/pygtk.pth $ ln -s /usr/lib/python2.7/dist-packages/gtk-2.0/
Finally, to check I typed 'python', and executed:
>>> import pygtk
It gave me no error, and therefore I knew its now available in my virtual env.
I'm using Ubuntu 14.04 (64-bit) on an intel Core i5.
