I am running an application in a virtual environment that needs access to DBus (to interact with the Network Manager, mainly).

I tried to install Dbus-Python with easyinstall and pip, but both fail.

When I try to do this:

(myvirtualenv)borrajax@borrajax-computer:~/Documents/Projects/VirtualEnvs/current_env$ bin/pip install dbus-python

Pip yells at me with:

Downloading/unpacking dbus-python
  Downloading dbus-python-1.1.1.tar.gz (596kB): 596kB downloaded
  Running setup.py egg_info for package dbus-python

I've had some issues with the python dbus bindings and their "accessibility" from my Python modules in the past, so I don't really know what may be the best way to set Dbus-Python in a virtual environment. Has anyone successfully achieved this? Or does anyone have an idea on how to do this?

Thank you in advance.

My suggestion is to install the system package for the Python DBUS bindings and then create the virtualenv with the --system-site-packages command line option to enable access to the system-wide Python packages (including the dbus package) from the activated virtualenv. For example on Debian/Ubuntu (or a derived distribution):

$ sudo apt-get install python-dbus
$ virtualenv --system-site-packages dbus-venv

To use the built in Python 3 venv module instead of virtualenv:

$ sudo apt-get install python-dbus
$ sudo apt-get install python3-venv
$ python3 -m venv --system-site-packages my_venv
