# Frequently Asked Questions (FAQ)

Caught out by a problem installing or running Pootle? We hope you’ll find some answers here. Ideal candidates are specific installation issues that we can’t integrate into the main docs. Feel free to provide updates with your own findings.

## Installation

### Does Pootle run under Python 3?

Pootle does not, yet, support Python 3 but it definitely is a goal.

Our first priority has been cleaning up the code and getting onto the latest version of Django. We’ve achieved that with Pootle 2.8.0.

We also want to be Django warning free, we’ve also achieved that in Pootle 2.8.0.

All of these where needed to ease to migration to Python 3.

Currently, we’re trying to eliminate Python 2 specific changes and we’re coding pylint checks to prevent any regression.

If you want to help make this happen sooner, patches are welcome.

### ModuleNotFoundError: No module named ‘syspath_override’

    File "/home/pootle/env/lib/python3.6/site-packages/pootle/runner.py", line 19, in <module>
       import syspath_override  # noqa
     ModuleNotFoundError: No module named 'syspath_override'

You are running Pootle using Python 3, change your virtual environment to Python 2 and try again.

Something like this will be needed to setup your virtual environment.

    $ mkvirtualenv --python=/path/to/python2 pootle

### locale.Error: unsupported locale setting

Pootle assumes that you have the `en_US.utf8` locale installed on your server. If for some reason your server does not include this (you’re not American or you are using a very minimal server) then you need to install that locale.

On a Debian based server simply run:

    $ sudo dpkg-reconfigure locales

### Installing missing system dependencies

Pootle may require you to install additional system dependencies. The majority of these relate to the installation of lxml, required by Pootle for XLIFF and other XML based support.

lxml requires compilation so we depend on build components as well as libraries for `libxml`, `libxslt` and Python.

On Debian based system the following will install all additional system requirements:

    $ sudo apt-get install build-essential libxml2-dev libxslt-dev python-dev python-pip zlib1g-dev
