rake db:migrate出现rake中止错误

Question

我正在学习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
rake aborted!

我在我应该在的目录中，这个目录是“site/simple_cms”。我已经安装了rake，还运行了"gem install bundle“和"bundle install”。我在目录中这样做了，然后在“站点目录”中，甚至在主目录中。没有什么是不同的。

Answer 1

/Users/lexi87/Sites/simple_cms/db/migrate/20130107145627_create_users.rb:14: syntax error, unexpected $end, expecting keyword_end

从上面的代码行“语法错误，意外的$end，期望的keyword_end”中，我认为您在迁移文件中添加了额外的结尾。只需检查您是否有多余的结尾，或者您错过了在迁移文件中添加结尾

Answer 2

对不起，我已经发现了问题所在。我在create users文件的底部遗漏了第二个"end“。

在整个教程中，我一直注意到，有一些行我必须添加，但它们并没有告诉您。现在我可以继续我的旅程了，谢谢你们的建议！
