Install Python-Dbus in virtualenv

Question

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     Traceback (most recent call last):       File "<string>", line 16, in <module>     IOError: [Errno 2] No such file or directory: '/home/borrajax/Documents/Projects/VirtualEnvs/current_env/build/dbus-python/setup.py'     Complete output from command python setup.py egg_info:     Traceback (most recent call last):    File "<string>", line 16, in <module>  IOError: [Errno 2] No such file or directory: '/home/borrajax/Documents/Projects/VirtualEnvs/current_env/build/dbus-python/setup.py'  ---------------------------------------- Command python setup.py egg_info failed with error code 1 in /home/borrajax/Documents/Projects/VirtualEnvs/current_env/build/dbus-python Storing complete log in /home/borrajax/.pip/pip.log 

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.

Answer 1

Go to your Venv follow this 2 steps :

1)sudo apt-get install libdbus-glib-1-dev libdbus-1-dev  2)pip install dbus-python 

verify with:

3) pip freeze 

if installed properly you will see: dbus-python==1.2.8

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
