Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform's standard location is), it's easy to end up in a situation where you unintentionally upgrade an application that shouldn't be upgraded. + +Read more about it in the `project documentation page <http://pypi.python.org/pypi/virtualenv/>`_. + + +Create and activate your dev environment +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +:: + + $ virtualenv </path/to/new/environment> + $ source </path/to/new/environment>/bin/activate + +Install python dependencies +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +You can install python dependencies with pip. If you do it inside your working environment, they will be installed avoiding the need for administrative permissions:: + + $ pip install -r pkg/requirements.pip + +.. _pyqtvirtualenv: + +Troubleshooting PyQt install inside a virtualenv +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If you attempt to install PyQt inside a virtualenv using pip, it will fail because PyQt4 does not use the standard setup.py mechanism. + +As a workaround, you can run the following script after creating your virtualenv. It will symlink to your global PyQt installation (*this is the recommended way if you are running a debian-based system*):: + + $ pkg/postmkvenv.sh + +A second option if that does not work for you would be to install PyQt globally and pass the ``--site-packages`` option when you are creating your virtualenv:: + + $ apt-get install python-qt4 + $ virtualenv --site-packages . + +Or, if you prefer, you can also `download the official PyQt tarball<http://www.riverbankcomputing.com/software/pyqt/download>`_ and execute ``configure.py`` in the root folder of their distribution, which generates a ``Makefile``:: + + $ python configure.py + $ make && make install + +.. note:: + this section could be completed with useful options that can be passed to the virtualenv command (e.g., to make portable paths, site-packages, ...). + + + +.. _policykit: + +Running openvpn without root privileges +--------------------------------------- + +In linux, we are using ``policykit`` to be able to run openvpn without run privileges, and a policy file is needed to be installed for that to be possible. +The setup script tries to install the policy file when installing the client system-wide, so if you have installed the client in your global site-packages at least once it should have copied this file for you. + +If you *only* are running the client from inside a virtualenv, you will need to copy this file by hand:: + + $ sudo cp pkg/linux/polkit/net.openvpn.gui.leap.policy /usr/share/polkit-1/actions/ + +Missing Authentication agent +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If you are running a desktop other than gnome or unity, you might get an error saying that you are not running the authentication agent. You can launch it like this:: + + /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 & |
