tilestache-server.py with postgis config fails with import error for osgeo

[radumas]

I'm running Ubuntu 16.04 with PostgreSQL 9.5 and PostGIS 2.2 installed from package archives. I installed pip install -U pillow modestmaps simplejson werkzeug uuid into a virtualenv running Python 2.7.12. I set up a configuration for a PostGIS layer based on the documentation.

When I run ./scripts/tilestache-server.py -c myconf.cfg I get the following error:

Error loading Tilestache config:

You need gdal installed and probably have to change the code to do a try to see if gdal is available through osgeo otherwise load it directly.

You can try this provider for PostGIS as well http://tilestache.org/doc/TileStache.Goodies.VecTiles.html

I'm having the same issue when I try to load my own layer via shapefile.

"layer_name":
    {
        "provider": {"name": "vector", "driver": "shapefile",
                          "parameters": {"file": "examples/layer_name.shp"}},
        "projection": "spherical mercator"
    },

gives me:

Error loading Tilestache config file: No module named osgeo

I have gdal installed via sudo apt-get build-dep python-gdal

Uh oh. I know I solved this but I don't remember how....

This ticket can be closed now as #316 added new documentation that suggests installing GDAL to prevent these issues going forward.
