为什么我会得到'`解析'；：（<；未知>；）：在此上下文中不允许映射值'；在Ruby中的YAML文件中

我在尝试用Ruby打开Yaml文件时遇到上述错误。我已经在这个验证器中检查了YAML，它已经通过了。我不确定我的YAML有什么问题会阻止它打开。有什么想法吗？这是YAML文件。我正试图用

yml=YAML:：load（file.open（'servers.yml'））打开文件。

您的问题在于没有冒号的行：

  - ps-overture-d01
    location: ps-overture-d01

将它们连接到下一行：

? "ps-overture-d01 location"
: ps-overture-d01

Ruby的YAML库不这样做，而是抛出一个错误。我不确定您是否打算将有问题的行连接起来，因此您需要了解如何正确调整YAML以提供合理的结构，或者将

id:

添加到这些行中的每一行

  - id: ps-overture-d01
    location: ps-overture-d01

以下是您的示例，以及我建议的更改：

你能不能再举一个例子，让我看看我应该怎么做？谢谢。谢谢。这很有帮助。你知道有什么好的资源我可以看YAML在线？
