Re: Error was: cannot import name 'GDALRaster in Window 8.1

The error after entered: gdalinfo --version

C:\Users\Prashant>gdalinfo --version

'gdalinfo' is not recognized as an internal or external command,

operable program or batch file.

Though, I have already installed gdal "gdal-201-1800-x64-core" into my system.

Your question regarding raster2pgsql has nothing to do with Django, so
please ask questions related to that somewhere else (for instance on
https://gis.stackexchange.com/ )

Regarding your first error, could you share the output of the following
command on your command line:

gdalinfo --version

(just to check if you have gdal installed)

I agree that the above error message is not useful for users that want
to use postgis but dont have gdal installed. Maybe its related to
something else, Postgis itself already requires gdal
