cannot do rake db:migrate

[kevinclcn]

I created a test table, but when I run rake db:migrate, I got below errors!

class CreateTests < ActiveRecord::Migration
  def change
    create_table :tests do |t|
      t.string :name
      t.string :label

      t.timestamps null: false
    end
  end
end

rake aborted! StandardError: An error has occurred, all later migrations canceled:
