Install Python-Dbus in virtualenv


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:

  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

I have 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?


Solution

  • When pip tries to install a package, it looks for setup.py, which dbus-python doesn't have, so you'll have to download the source and compile it manually. Shouldn't be too hard:

    PYTHON=python3.3 ./configure --prefix=/tmp/dbus-python
    make
    make install
    

    then you can move the compiled files to your virtualenv.


    edit: starting with dbus-python-1.2.2 (released 2016-02-22) dbus-python has a setup.py, so pip should be able to install it
