我刚刚将一个项目移动到另一台服务器，并且似乎遇到了与Ruby 1.9.2以来可用的新的新哈希参数相关的问题。当我运行rails s时，我收到以下错误

错误引用以下行
Myapp::Application.config.session_store :cookie_store, key: '_myapp_session'
我真的不认为上面的代码行是问题所在。如果我删除键：'_ myapp_session'或将其恢复为Ruby 1.8.X样式我只是得到下一个哈希参数错误。
我移动到的服务器最初在服务器上运行了Ruby 1.8.7。我已将ruby更新为1.9.3。当我运行ruby -v时，我得到ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
我不确定为什么我仍然遇到哈希问题。有没有人遇到过类似的问题？

您可能需要检查路径，它似乎正在使用1.8 ruby树中的可执行文件。升级时，您可能需要重新安装宝石..这种情况是rvm是安装ruby的首选方式的一个原因。

你应该发布你怀疑有罪的代码，用这么少的线索很难回答。
关于新样式的一个问题是，如果散列中的所有键都是符号，则只能使用它，这可能是问题所在。
