I'm trying to merge the above two files and get the following error
C:\Node\node_modules>node .bin/geojson-merge GB.json de.json > c:\node\node_modules\out.json
C:\Node\node_modules.bin\geojson-merge:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\,/,g')")
^^^^^^^

That doesn't appear to be coming from geojson-merge. Perhaps try updating your version of node? That line looks Linux specific, which might be a problem running on windows.
