没有实际的迁移文件很难说，但请确保您的cashanalytics/db/migrate/20130614160852_add_first_name_last_name_user_type_values_to_user.rb文件看起来像这样：

class AddFirstNameLastNameUserTypeValuesToUser < ActiveRecord::Migration[7.1]
  def change
    add_column :user, :first_name, :string
    add_column :user, :last_name, :string
    # guessing the data type here.May also be a reference.
    add_column :user, :user_type, :integer
  end
end
