Why is using ruby 2.7.0 when the image uses 2.7.5?

Any hint on how to solve this issue would be highly appreciated.

Probably this isn’t relevant for you anymore, but for future reference here’s what solved the same problem for me.

Clearing the dependency cache did the trick for me (https://support.circleci.com/hc/en-us/articles/115015426888-Clear-Project-Dependency-Cache). I simply add a versioning to my cache keys that I can bump when I need to.

I have no idea why this cache error occurs however, since ruby version is printed into the lock file and should trigger a cache invalidation.
