Chef Workstation rspec error

After doing a "cinc exec bundle install" the rspec-core version jumps up:
Installing rspec-core 3.12.2

However, when trying to then run rspec on tests that require "chefspec", I'm getting this:
Failure/Error: require 'chefspec'

  Unable to activate rspec-3.11.0, because rspec-core-3.12.2 conflicts with rspec-core (~> 3.11.0)

After doing a little digging it appears like inspec is required, and doesn't want a version newer than 3.11.0: inspec | | your community gem host

How have you folks gotten passed this? Pinning the rspec version seems wrong, but was the only way I've resolved this so far.
