build error

object SourceInfo is not a member of package chisel3.experimental
import chisel3.experimental.SourceInfo

error when I build playground
how to fix this ??

Start with the playground build and the reported import of chisel3.experimental.SourceInfo. Check the Chisel dependency and package contents to determine why SourceInfo is unavailable. Done means the playground builds without this error, with the required dependency or source usage identified.
