ruby-on-rails - Rake 由于序列无效而中止

Question

我正在用新内容更新我服务器上的一个 Rails 应用程序。它工作正常，直到前一天。现在，当我尝试使用 rake 或使用任何 rake 命令迁移我的数据库时，出现以下错误:

rake aborted!
rake aborted!

(See full trace by running task with --trace)

我的本​​机ruby版本是:2.0.0p0 我的服务器 ruby​​ 版本是:ruby 1.9.3p194

是不是因为我需要将我服务器上的 ruby​​ 版本更新到 2.0.0p0

谢谢
