ruby-on-rails - 我得到 "found character that cannot start any token while scanning for the next token"

Question

我已经在我的笔记本电脑上运行 Ruby on Rails 大约一个月了，但是当我想在这个实例中运行服务器时(它在几个小时前工作正常)我现在收到这条消息。请问如何让服务器再次运行？

YAML 不接受 TAB 字符 (\t) 进行缩进。在您的 config/application.yml 中查找那些并替换为 2 个空格。

(或者可能存在其他语法错误，正如 Ryan 所建议的那样。但我敢打赌这个错误)
