此处不允许使用映射值-YAML

Question

我已经为我的主要python代码准备了一个YAML文件，加载时出现错误，请在YAML文件中建议更正。

此处不允许使用映射值-第4行，第9列

yaml.scanner.ScannerError: mapping values are not allowed here
  in "C:\Users\rajangra\PycharmProjects\jinja2/yaml_input/input.yaml", line 4, column 9

Process finished with exit code 1

我尝试更改许多参数，但仍然出现相同的错误

  - SGC
    ring:
    - Rosebank Ring 7
      hostname:
      - SGC_CrownLongmeM_SARA-1

诸如SGC ring和Rosebank Ring 7 hostname之类的多行普通标量不能用作映射键，请引用它们

region:
  - 'SGC
    ring':
    - 'Rosebank Ring 7
      hostname':

或将它们放在一行上：

region:
  - SGC ring:
    - Rosebank Ring 7 hostname:

（另一种可能性是您忘记在ring和hostname之前插入破折号）。
