Psych :: SyntaxError無法解析YAML

Question

我在運行在fedora 16 Rails 2.3.5和Ruby 1.9.2.p320上的Rails應用程序中遇到問題。該應用程序在Ubuntu 11.10上運行良好。當我運行rails服務器並打開任何控制器時出現以下錯誤。

精極度緊張:: SyntaxError錯誤在controllername＃actionname

無法解析YAML

我曾嘗試採用下面的技巧，但它不是爲我工作。

我已經添加在配置以下行/的boot.rb

require 'yaml' 

YAML::ENGINE.yamler = 'syck'

舊YAML解析器不喜歡有標籤，但只有空格。您可能需要檢查YAML文件以查看它是否在第18行有任何選項卡。如果是這種情況，您可能需要修復YAML文件或升級解析器。
