Grpc not caching

Build Environment Caching Dependencies
, ,
1

New to circleci so bare with me :sweat_smile:
Trying to just lint an express app that lives in the backend/core folder of our repo. I implemented the npm caching example to speed up builds but one of our dependencies is grpc for gcloud and it reinstalls all over again each time.

Any ideas what I can do here?
