我正在关注Lynda ruby on rails教程。我被要求输入“rake db：migrate”。然而，这是我收到的错误。
lexi87$ rake db:migrate

我在我应该成为的目录中，这是“sites / simple_cms”。我已经安装了rake并且还运行了“gem install bundle”和“bundle install”。我在目录中完成了这个，然后在“站点目录”甚至主目录中。没有什么能有所作为。

从上面的代码行“语法错误，意外的$ end，期待keyword_end “，我认为您在迁移文件中添加了一个额外的结尾。只需检查您是否有额外的结束，或者您错过了结束迁移文件

抱歉，我发现了什么问题。我在创建用户文件的底部错过了第二个“结束”。
我在整个教程中都注意到，我必须添加一些他们没有告诉你的行。现在我可以继续我的旅程，感谢你的建议！
