我在笔记本电脑上运行Ruby on Rails已经有一个月了，但是当我想在这个示例中运行服务器时（几个小时前它还运行得很好），我现在收到了这个消息。请问我怎样才能让服务器再次运行呢？

YAML不接受TAB字符（
\t）作为缩进。请在config/application.yml中查找这些字符并替换为2个空格。（* 或者可能有其他语法错误，如Ryan所建议的。但我打赌这一个 *）

这个错误来自于Figaro gem，这表示您可能在
config/application.yml中有语法错误。请仔细检查这个档案是否有任何不正确的YAML语法。isr3a4wc3#
可能不是你的具体例子，但堆栈溢出的标题导致我在这篇文章，所以对于那些工作与此错误，它可能是由于：
一个翻译的yml或任何yaml...
字符串插值前后没有双引号

我也有同样的问题。我肯定是制表符（\t）的问题。请用2个空格替换。

你应该检查所有包含YAML的重要配置文件。我在尝试
rake db:seed时也遇到了同样的错误，结果发现我在config/database.yml的注解块中有TAB字符。如果您不确定，请使用一些在线YAML解析器，例如http://yaml-online-parser.appspot.com/。

当其中一个yaml文件获得语法错误“* yaml中没有选项卡 *"时会发生此错误，yaml文件可能是
database.yaml，application.yaml等。wwtsj6pe7#
当你在yaml中使用未声明的变量时，也会发生这个问题，这会导致缩进问题。在我的例子中，类似于：
因此，请确保声明了所有变量。
