推荐答案

旧的 YAML 解析器不喜欢有制表符，只有空格.您可能需要检查您的 YAML 文件，看看它在第 18 行是否有任何选项卡.如果是这种情况，您可能需要修复您的 YAML 文件或升级解析器.

Older YAML parsers did not like having tabs but only spaces. You might want to check your YAML file to see if it has any tabs at line 18. If this is the case, you might want to either fix your YAML files or upgrade the parser.
