ArgumentError: Index name 'index_rates_on_rater_id' on table 'rates' already exists

When running migrations Rails 5.1

Got this too. AFAIK, this is caused by the second migration created by Ratyrate, the one with name "[whatever]_create_rates.rb". Ratyrate attempts to create an index, add_index :rates, :rater_id, but, as I see, it is automatically created by the line t.belongs_to :rater. See here, "Add an appropriate index. Defaults to true".
I solved it by simply commenting the index line before migrating. Might need some extra attention. I'm going to try and see which code generates it.
