當我嘗試做耙分貝我得到這個錯誤，當遷移語法錯誤：遷移：耙分貝：嘗試做遷移

這裏是我的遷移表：

bundle exec rake test:prepare 
class CreateMicroposts < ActiveRecord::Migration 
    def change 
    create_table :microposts do |t| 
     t.string :content 
     t.integer :user_id 
     t.timestamps 
    end 
    add_index :microposts,[:user_id,:created_at] 
    end 
end

有誰知道爲什麼會發生這種情況，以及我如何解決這個問題，以便在遷移時不會給我這個錯誤？

任何這運氣了嗎？ – zeantsoi

從遷移文件開始刪除這一切：bundle exec rake test:prepare

bundle exec rake test:prepare從命令行中運行。細分，bundle exec在當前包的上下文中執行腳本; rake test:prepare（或更可能是rake db:test:prepare）是要執行的rake任務。

您應該遷移內容如下：

class CreateMicroposts < ActiveRecord::Migration 
    def change 
     create_table :microposts do |t| 
      t.string :content 
      t.integer :user_id 
      t.timestamps 
     end 
     add_index :microposts,[:user_id,:created_at] 
    end 
end

謝謝！我是紅寶石noob，這工作:) – Farhadam

bundle exec rake test:prepare不是Ruby--它不應該在您的遷移文件中。
