如何在TileStache中將Geojson設置爲數據源

我已經在我的服務器中成功安裝了TileStache。現在我有一個geojson文件，並希望通過TileStache提供它。我是TileStache的新手，我無法找到如何在TileStache中設置Geojson的清晰說明。我能找到的最佳解釋是here，但它使用shp文件作爲數據源。如何在TileStache中將Geojson設置爲數據源

我想知道如何使用Geojson作爲數據源來設置它。

我嘗試添加一個tes層的配置文件，所以我的配置文件看起來像這樣：

{ 
    "cache": 
    { 
    "name": "Test", 
    "path": "/tmp/stache", 
    "umask": "0000" 
    }, 
    "layers": 
    { 
    "osm": 
    { 
     "provider": {"name": "proxy", "provider": "OPENSTREETMAP"}, 
     "png options": {"palette": "http://tilestache.org/example-palette-openstreetmap-mapnik.act"} 
    }, 
    "example": 
    { 
     "provider": {"name": "mapnik", "mapfile": "examples/style.xml"}, 
     "projection": "spherical mercator" 
    }, 
     "tes":{ 
       "provider": { 
         "name": "vector", "driver": "GeoJSON", 
         "parameters": {"file": "tes.geojson"}, 
         "properties": [] 
       } 
     } 
    } 
}

當我試圖用tilestache-server.py -c /etc/TileStache/tilestache.cfg運行，它給我這樣的錯誤：

我無法弄清楚什麼是錯的。

ImportError: No module named osgeo

您缺少GDAL library。安裝起來可能非常棘手，我使用PPA ppa:ubuntugis/ubuntugis-unstable在Ubuntu 14.04上運行，在GIS Stackexchange上閱讀this post中的說明。
