I start to learn Geotrellis, when I compile the demo of "geotrellis-friction-surface", I met the error
_ ##[error] "geotrellis-friction-surface-master\src\main\scala\ingest\OSM.scala:149:21: could not find implicit value for evidence parameter of type geotrellis.util.Component[vectorpipe.LayerMetadata[geotrellis.spark.SpatialKey],geotrellis.spark.Bounds[geotrellis.spark.SpatialKey]]
[error] env.writer.write(env.layer, rdd, ZCurveKeyIndexMethod)"._

I don't know how to Initialization this implicit value. I read the scala API , and found it need an implicit value for arg6: GetComponent[M, Bounds[K]])
