Angular compiling library warns: No name was provided for.?

using angular-cli: @ 6.0.0 to create a new library, that references some peerDependencies
prompts No name was provided for external module "xxx" in output.globals when compiling.

Excuse me, what does this mean? How can it be removed? Where can I configure output.globals?
