ruby bundler: Sorry, you can't use byebug without Readline


On OS/X Sierra, after recently running a brew update I started receiving the error message Sorry, you can't use byebug without Readline when trying to run some rake tasks in my ruby project folder. I observed this in projects and gems that include byebug or pry in their Gemfile or gem.spec.

      mime-types (>= 0)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
