yarn install v1.22.5
error An unexpected error occurred: “/home/circleci/repo/package.json: Unexpected token / in JSON at position 288”.

message everytime I try to deploy

It’s saying that there is an issue with your package.json. Can we see that? Or maybe run it through and online JSON validator? My guess would be that there is some typo in that file. A good IDE should flag it for you.
