Как исправить 'ArgumentError: неправильное количество аргументов (задано 2, ожидается 0..1) в Ruby on Rails

Я создаю новые таблицы с помощью mysqlite и Ruby on Rails. Почему мой рейк прерывается и как я могу это исправить?

Обновил мою версию Ruby on Rails и запустил 'bundle install'. Понятия не имею, почему я получаю эти сообщения, но, похоже, они связаны с управлением версиями Ruby.

Модель ингредиента 

class Ingredient < ActiveRecord::Base
    attr_accessor :picture, :name, :price, :quantity
end

Таблица ингредиентов 

class CreateIngredients < ActiveRecord::Migration[5.2]
  def change
    create_table :ingredients do |t|
      t.string :name
      t.decimal :price
      t.integer :quantity

      t.timestamps
    end
  end
end

Моя таблица не создана, и я получаю это сообщение об ошибке: 

♥ rake db:migrate
== 20190702014335 CreateIngredients: migrating ================================
-- create_table(:ingredients)
   -> 0.0031s
