我已经在笔记本电脑上运行 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（几个小时前它运行良好），我现在收到了这条消息。请问如何让服务器重新运行？

YAML 不接受 TAB 字符 ( \t) 用于缩进。寻找你的那些config/application.yml并用 2 个空格替换。

（或者可能有其他语法错误，正如 Ryan 所建议的那样。但我打赌这个）

此错误源自Figaro gem，它向我表明您可能在config/application.yml. 仔细检查此文件是否有任何不正确的 YAML 语法。

可能不是您的具体示例，但 Stack Overflow 的标题导致我出现在这篇文章中，因此对于那些处理此错误的人来说，这可能是由于：

en.yml 或翻译 yml 或任何 yaml...

字符串插值周围没有双引号

points:
  other: %{points} points

更正：

points:
  other: "%{points} points"

我和你有同样的问题。我确定它的 TAB 字符 (\t) 问题。请替换为 2 个空格。

您应该检查所有包含 YAML 的重要配置文件。我在尝试时遇到了同样的错误rake db:seed，结果发现我在config/database.yml.

如果不确定，请使用一些在线 YAML 解析器，即http://yaml-online-parser.appspot.com/。

当 yaml 文件之一出现语法错误“ yaml 中没有选项卡”、yaml 文件可能database.yaml等时，会发生此错误application.yaml。

下一行不应该有任何空格
