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

我在我应该在的目录中，即“sites/simple_cms”。我已经安装了 rake 并且还运行了“gem install bundle”和“bundle install”。我在目录中完成了此操作，然后在“站点目录”甚至主目录中完成了此操作。没什么大不了的。

【问题讨论】：

显示文件 db/migrate/20130107145627_create_users.rb 的内容
类 CreateUsers 25 t.string "last_name", :limit => 50 t.string "email", :default => "", :null => false t.string "password", :limit => 40 t.timestamps end end def self.down drop_table :users end
找到答案，需要额外的“结束”

【解决方案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 $end，期待关键字_end "，我认为您在迁移文件中添加了一个额外的结尾。只需检查您是否有多余的结尾或者您错过了在迁移文件中添加结尾

【讨论】：

我找到了答案，但是现在不允许我发布答案。我在底部缺少了一个额外的“结束”。

【解决方案2】：

抱歉，我发现了问题所在。我在创建用户文件的底部缺少第二个“结束”。

在整个教程中，我一直注意到有些行我必须添加，但他们并没有告诉你。现在我可以继续我的旅程了，谢谢大家的建议！
