C:\Sites\omniauth-tutorial>rake db:migrate 
== 20160904075837 CreateUsers: migrating  ====================================== 
-- create_table(:users) 
-- add_index(:users, :provider) 
rake aborted! 
StandardError: An error has occurred, this and all later migrations canceled:

これは私のマイグレーションファイルです

class CreateUsers < ActiveRecord::Migration 
    def change 
    create_table :users do |t| 
     t.string :provider, null: false 
     t.string :uid, null: false 
     t.string :name 
     t.string :location 
     t.string :image_url 
     t.string :url 
     add_index :users, :provider 
     add_index :users, :uid 
     add_index :users, [:provider, :uid], unique: true 

     t.timestamps null: false 
    end 
    end 
end 

Plsはエラーメッセージですアイデアこれはどのように解決することができますか？

あなたはcreate_table

class CreateUsers < ActiveRecord::Migration 
    def change 
    create_table :users do |t| 
     t.string :provider, null: false 
     t.string :uid, null: false 
     t.string :name 
     t.string :location 
     t.string :image_url 
     t.string :url 

     t.timestamps null: false 
    end 

    add_index :users, :provider 
    add_index :users, :uid 
    add_index :users, [:provider, :uid], unique: true 
    end 
end
