问题
I installed ipython in a virtual env (1.13 with 2.7.2) and tried ipython -gui=gtk but still got the basic terminal interface with no %paste support for example.
Now I tried installing pygtk but no success there either.
I'm running Crunchbang linux with OpenBox WM.

I've tried to pip install pygtk within the virtualenv I've activated but no luck.

回答1:
Since you are running a debian-based distribution; you can save yourself some headaches and simply sudo apt-get install ipython (and sudo apt-get install ipython3 if you want to play with Python 3).
This will ensure that the proper GTK bindings are installed as well. This is the most supported way.
Latest versions of ipython have auto-detection of virtualenvironments.

I first installed gi with pip (on ubuntu) and got the same error, without a virtualenv. My solution was to uninstall gi:
sudo -H pip uninstall gi
and then install using:
sudo apt-get install --reinstall python-gi
