Easiest is to first install the Stetl-dependencies (see below) and then install and maintain Stetl on your system as a Python package (pip is preferred).
(sudo) pip install stetl
or
easy_install stetl
Alternatively you can download Stetl from Github: by cloning (preferred) or downloading: https://github.com/justb4/stetl/archive/master.zip and then install locally
(sudo) python setup.py install
Try the examples first. This should work on Linuxes and Mac OSX. Windows installation may be more involved depending on your local Python setup. Platform-specific installations below.
You may also want to download the complete .tar.gz distro from PyPi: https://pypi.python.org/pypi/Stetl . This includes the examples and tests.
Docker: Since version 1.0.9 Stetl also can be installed and run via Docker. See Install with Docker below.
Stetl depends on the following Python packages:
GDAL requires the native GDAL/OGR tools to be installed.
lxml http://lxml.de/installation.html requires the native (C) libraries:
When using the Jinja2 templating filter, Jinja2TemplatingFilter, see http://jinja.pocoo.org:
Most packages should be able to be installed by apt-get or Python pip or easy_install.
Optional: Python package dependencies
sudo apt-get install python-setuptools
sudo apt-get install python-dev
sudo apt-get install libpq-dev
libxml2/libxslt libs are usually already installed. Together with Python lxml the total install for lxml is.
apt-get of yum install libxml2
apt-get of yum install libxslt1.1
apt-get of yum install python-lxml
GDAL (http://gdal.org) with Python bindings
apt-get of yum install gdal-bin
apt-get of yum install python-gdal
the PostgreSQL client library for Python psycopg2
sudo easy_install psycopg2
Python package argparse if you have Python < 2.7
sudo easy_install argparse
Best is to install GDAL and python using the OSGeo4W Installer from http://trac.osgeo.org/osgeo4w.
Only Psycopg2 needs explicit installation. Many install via: http://www.stickpeople.com/projects/python/win-psycopg. Once the above has been installed you should have everything required to run Stetl.
Alternatively you may use Portable GIS. Still you will need to manually install psycopg2. See http://www.archaeogeek.com/portable-gis.html for details.
If you installed via Python ‘pip’ you can check if you run the latest version
stetl -h
You should get meaningful output like
2013-09-16 18:25:12,093 util INFO running with lxml.etree, good!
2013-09-16 18:25:12,100 util INFO running with cStringIO, fabulous!
2013-09-16 18:25:12,122 main INFO Stetl version = 1.0.3
usage: stetl [-h] -c CONFIG_FILE [-s CONFIG_SECTION] [-a CONFIG_ARGS]
Especially check the Stetl version number.
Try running the examples when running with a downloaded distro.
cd examples/basics
./runall.sh
Look for any error messages in your output.
One of the cleanest ways to use Stetl is via Docker. Your environment needs to be setup to use Docker and probably you want to use some tooling like Vagrant. The author uses a combination of VirtualBox with Ubuntu and Vagrant on Mac OSX to run Docker, but this is a bit out of scope here.
Assuming you have a working Docker environment, there are two ways to install Stetl with Docker:
