你好，谢谢你为此付出的努力，
我是RoR的新手，我正在关注Michael Hartl撰写的RUBY ON RAILS TUTORIAL，当我尝试在heroku中迁移数据库时，我真的陷入了这个错误（我知道语法错误是什么意思（结束），但我仍然无法解决它）
heroku run rake db:migrate

我已经完成了研究，发现问题出在END的结尾或结尾，但是我尝试添加和删除结尾...没有运气。奇怪的是，即使添加或删除了ENDS，错误也完全相同。这是迁移文件
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name
t.string :email
t.timestamps
end
end
end
非常感谢，希望您能提供帮助。快乐编码
发现了问题。问题是我在本地进行更改，但是缺少提交更改，将其推送到git，然后将其拉到heroku实例中。
一旦完成，就可以毫无问题地运行数据库迁移。
顺便说一句，我在最上面发布的代码是正确的，但是当我第一次推送它时，它在定义类时出现语法错误。
