ruby - 为什么我得到 '` parse' : (): mapping values are not allowed in this context' in YAML file in Ruby

Question

尝试在 Ruby 中打开我的 Yaml 文件时出现上述错误。我已经检查了这个验证器中的 YAML，它已经通过了 http://yamllint.com/ .我不确定我的 YAML 有什么问题会阻止它打开。有任何想法吗？这是 YAML 文件。我正在尝试使用 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

什么 http://yamllint.com/所做的是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，也许将 id: 添加到这些行中的每一行？

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

这是您的示例，其中包含我建议的更改:
