Removing grape_logging from the project fixes the issue. @dblock says:

If this fixes that feels like grape_logging should be doing a require 'grape'. Open an issue in that repo.

Seems like this repo needs to require 'grape' somewhere.

UPDATE: If I move require 'grape_logging' to spot in the load order after I am sure grape has been loaded, then this error goes away. This gem, as is, doesn't load grape properly on it's own, but allowing bundler to load grape works.

In other words, if I have a require 'grape_logging' early on, before bundler loads my environment, then I get this error with latest version of grape.

Hat tip to @robert-hromej who had the right idea.
