Getting 'cannot load such file -- rubocop-rspec'

[mariano1deg]

We are getting cannot load such file -- rubocop-rspec when trying to commit a migration using this gem.

We are using ruby 2.4.5, which is installing rubocop >= 0.60.0 (0.64.0 actually).

Doesn't this gem currently support rubocop 0.64 or is this a different issue?

Thanks.
